▼ In this dissertation, we systematically construct non-extremal charged rotating
anti-de Sitter black hole solutions in four, five and seven dimensions. In four dimensions,
we first obtain the rotating Kerr-Taub-NUT metric with four independent
charges, as solutions of N = 2
supergravity coupled to three abelian vector multiplets
by the solution generating technique. Then we generalise the four-dimensional rotating
solutions to the solutions of gauged N = 4
supergravity with charges set pairwise
equal. In five dimensions, the most general charged rotating black hole solution has
three charge and two rotation parameters. We obtain several special cases of the general
solution. To be specific, we obtain the first example of a non-extremal rotating
black hole solution with two independent rotation parameters, which has two charge
parameters set equal and the third vanishing. In another example, we obtain the nonextremal
charged rotating black hole solution with three charge parameters set equal
and non-equal rotation parameters. We are also able to construct the single-charge
solution with two independent rotation parameters. In seven dimensions, we obtain
the solution for non-extremal charged rotating black holes in gauged
supergravity, in
the case where the three rotation parameters are set equal. There are two independent
charges, corresponding to gauge fields in the U(1) ? U(1) abelian subgroup of
the SO(5) gauge group.

▼ This thesis examines exact solutions to gauged and ungauged supergravity theories in space-time dimensions D⩾5 as well as various instabilities of such solutions.
I begin by using two solution generating techniques for five dimensional minimal ungauged supergravity, the first of which exploits the existence of a Killing spinor to generate supersymmetric solutions, which are time-like fibrations over four dimensional hyper-Kähler base spaces. I use this technique to construct a supersymmetric solution with the Atiyah-Hitchin metric as the base space. This solution has three independent parameters and possesses mass, angular momentum, electric charge and magnetic charge. Via an analysis of a congruence of null geodesics, I determine that the solution contains a region with naked closed time-like curves. The centre of the space-time is a conically singular pseudo-horizon that repels geodesics, otherwise known as a repulson. The region exterior to the closed time-like curves is outwardly geodesically complete and possesses an asymptotic region free of pathologies provided the angular momentum is chosen appropriately.
The second solution generating technique exploits a hidden G2 symmetry in five dimensional minimal supergravity. I use this hidden symmetry approach to construct the most general black string solution in five dimensions, which is endowed with mass, angular momentum, linear momentum, electric charge and magnetic charge. This general black string satisfies the first law of thermodynamics, with the Bekenstein-Hawking entropy being reproduced via a microstate counting in terms of free M-branes in the decoupling limit. Furthermore it reduces to all previously known black string solutions in its various limits. A phase diagram for extremal black strings is produced to draw conclusions about extremal black rings, in particular why supersymmetric black rings exhibit a lower bound on the electric charge. The same phase diagram further suggests the existence of a new class of supersymmetric black rings, which are completely disconnected from the previously known class.
A particular limit of this general black string is the magnetically charged black string, whose thermodynamic phase behaviour and perturbative stability were previously studied but not very well understood. I construct magnetically charged topological solitons, which I then show play an important role in the phase structure of these black strings. Topological solitons in Einstein-Maxwell gravity, however, were previously believed to generically correspond to unstable "bubbles of nothing" which expand to destroy the space-time. I show that the addition of a topological magnetic charge changes the stability properties of these Kaluza-Klein bubbles and that there exist perturbatively stable, static, magnetically charged bubbles which are the local vacuum and the end-point of Hawking evaporation of magnetic black strings.
In gauged supergravity theories, bubbles of nothing are stabilised by the positive energy theorem for…

▼ We determine the conditions under which half-maximal matter coupled gauged
supergravity
in seven dimensions admits a chiral circle reduction to yield a matter coupled
gauged
supergravity in six dimensions with 8 real supersymmetry. Solving these
conditions we nd that the SO(2; 2) and SO(3; 1) gauged 7D supergravities give a
U(1)R, and the SO(2; 1) gauged 7D
supergravity gives an Sp(1)R gauged chiral 6D
supergravity coupled to certain matter multiplets. In the 6D models obtained, with
or without gauging, we show that the scalar fields of the matter sector parametrize
the coset SO(p + 1; 4)=SO(p + 1) SO(4), with the (p + 3) axions corresponding to
its abelian isometries.
We then derive the necessary and sufficient conditions for the existence of a Killing
spinor in N = (1; 0) gauge 6D
supergravity coupled to a single tensor multiplet, vector
multiplets and hypermultiplets. We show that these conditions imply most of the eld
equations. We also determine the remaining equations that need to be satised by an
exact solution. In this framework, we nd a novel 1=8 supersymmetric dyonic string
solution with nonvanishing hypermultiplet scalars. The activated scalars parametrize
a 4 dimensional submanifold of a quaternionic hyperbolic ball. The key point is that
we employ an identity map between this submanifold and the internal space transverse
to the string worldsheet, thereby nding a higher dimensional generalization of Gell-
Mann-Zweibach tear-drop solution.

▼ In gravity theory in four dimensions, there are
three possible topological terms which can be added to the
Lagrangian density. These are the Nieh Yan, Pontryagin and Euler
terms. Here we investigate the e_ect of these terms in the context
of canonical SU(2) formulation of gravity. We set up a general
SU(2) formulation for gravity including all three terms. The theory
contains three topological parameters associated with the three
terms. Finally, we study what could be a suitable quantum framework
for gravity in which one of these parameters, namely the
Barbero-Immirzi parameter, can be interpreted as a vacuum angle
exactly like the theta parameter in gauge
theories.

▼ We consider type 2B superstring consistent backgrounds with U(1)
d global isometry. The moduli-generating group for such backgrounds is SO(d,d,R). We focus on the subgroup whose elements correspond to the gamma-deformations introduced by O. Lunin and J. Maldacena. From the point of view of
supergravity, these deformations can be used as a classical solution generating technique. The action of SO(d,d,R) on the NS-NS and R-R bosonic fields of type 2B
supergravity is presented. In this framework, we obtain the gamma-deformed AdS
5xS5 solution, known as the Lunin-Maldacena solution, and show subsequently that it satisfies the equations of motion derived from a type 2B
supergravity covariant action. Finally, we consider several gamma-deformations of a 1/4-supersymmetric AdS
2xS2xT6 type 2B solution. We present these new solutions and determine their amount of unbroken supersymmetries.

▼ There are hints that the N=1 anti-de Sitter supersymmetry algebra for in four dimensions permits 1/2-BPS states at the bound E=|J|. Recent literatures suggest that for N=2 with zero magnetic and electric charge, BPS states occurs at the same bound, which correspond to the ultra spinning limit. The main goal of the thesis is to determine whether or not there are BPS rotating black holes in N=1, D=4 anti-de Sitter
supergravity. We first gave a review of the necessary background on Kerr black holes, the N=1 supersymmetry algebra and
supergravity. We prove the non-existence of BPS Kerr black holes in flat space and presented the current work on solving for the complete set of Killing spinors of Kerr-AdS.

▼ We have a look at compactification as a special way of explaining why we only observe 4 spacetime dimensions although theories as string or M-theory require more. In particular, we treat compactification of 11-dimensional supergravity, which is the low energy limit of M-theory, on S4 x T3. At first, we present the basic ideas behind those theories and compactification. Then we introduce important concepts of supersymmetry and supergravity. Afterwards, our particular case of compactification is treated, where we first review the results for the compactification on S4 before we calculate the scalar potential from the reduction ansatz for a so-called twisted torus.

▼ Supersymmetry is the most natural framework for physics above the TeV scale, and the corresponding framework for early-Universe cosmology, including inflation, is supergravity. No-scale supergravity emerges from generic string compactifications and yields a non-negative potential, and is therefore a plausible framework for constructing models of inflation. No-scale inflation yields naturally predictions similar to those of the Starobinsky model based on R + R2 gravity, with a tilted spectrum of scalar perturbations: ns∼0.96, and small values of the tensor-to-scalar perturbation ratio r < 0.1, as favored by Planck and other data on the cosmic microwave background (CMB). In this thesis we introduce a novel no-scale inflationary model that averts the stabilization problem of supergravity models; to study it we develop a multi-field formalism applicable to supergravity models. We discuss the low-energy phenomenology of generic no-scale models and its connection to the lifetime of the inflaton. We use our results to analyze the constraints on these models imposed by CMB measurements, which through the calculation of the number of e-folds N_* , we relate to constraints on the inflaton decay rate and other parameters of specific no-scale inflationary models. Finally, we revisit gravitino production following inflation, including thermal and non-thermal effects, and discuss the potential implications of upper limits on the gravitino abundance for no-scale models of inflation. Our results may provide insights into the embedding of inflation within string theory as well as its links to collider physics.

▼ This thesis is divided into three main parts. In the first of these (comprising chapters 1 and 2) we present the physical context of the research and cover the basic geometric background we will need to use throughout the rest of this thesis. In the second part (comprising chapters 3 to 5) we motivate and develop the strong homogeneity theorem for supergravity backgrounds. We go on to prove it directly for a number of top-dimensional Poincaré supergravities and furthermore demonstrate how it also generically applies to dimensional reductions of those theories. In the third part (comprising chapters 6 and 7) we show how further specialising to the case of symmetric backgrounds allows us to compute complete classifications of such backgrounds. We demonstrate this by classifying all symmetric type IIB supergravity backgrounds. Next we apply an algorithm for computing the supersymmetry of symmetric backgrounds and use this to classify all supersymmetric symmetric M-theory backgrounds.

▼ This work addresses two of the main open problems of particle physics: the discovery of supersymmetry and the identification of the constituents of dark matter. Supersymmetry is a proposed symmetry of nature whose extension, the supergravity theory, is widely believed to govern the nature of physics beyond the standard model. One of the predictions of supersymmetry and supergravity theories is the existence of new particles, called sparticles, which are counterparts of the existing matter in the universe. Their discovery is essential for the confirmation of supersymmetry and supergravity as the governing frameworks for physics beyond the standard model. The work of this thesis focuses on the exploration of supersymmetry and supergravity models which can simultaneously explain – through the phenomenon of coannihilation – the observed amount of dark matter, i.e., about 27% of the total mass and energy of the universe. This work describes models for which the properties of sparticles are consistent with the observed properties of dark matter in the universe and discusses strategies for the discovery of sparticles at the Large Hadron Collider, which is currently collecting data at a center of mass energy of 13 TeV. The possibility of direct detection of dark matter in deep underground experiments such as LUX-ZEPLIN is also explored.

▼ Firstly, scalar quark mass matrices are calculated for a non-minimal SU5 N=l supergravity theory with realistic fermion masses. The squark mixing matrices, analogues of the Kobayashi-Maskawa matrices for quarks, are also calculated and have significant off-diagonal entries. Thus, there are non-zero flavour-changing gaugino interactions between 'up' quarks and 'up' squarks in the non-minimal model. This is in contrast to the case for minimal SU5 . It is shown that in the non-minimal model flavour-changing gluino interactions contribute to the proton decay modes p → μ+K0, ῡμK+ at about the same rate as the mode p → ῡμK+ mediated by Wino exchange. Contributions to the KL-KS mass difference from flavour-changing gluino and wino interactions are small. Secondly, for a finite N=2 globally supersymmetric theory it is shown that the set of finiteness-preserving soft operators previously derived by Parkes and West is incomplete. The complete set of 1-loop finite operators is derived by a graphical analysis, and it is shown that most of these preserve finiteness to all orders. The low-energy N=2 model of Del Aguila et al. is reviewed, and it is shown that new constraints on the τ-neutrino mass require an unnaturally high scale of supersymmebry breaking in the model.

▼ An unexpectedly tiny cosmological constant (i.e. the vacuum energy density) Λ = 10-122 MP4 has been observed since the 1990s. This thesis examine the statistical interpretation of the cosmological constant problem in supergravity models. The racetrack model in Type IIB string theory is studied in the presence of leading α-correction in flux compactification. We show that a class of de-Sitter vacua is generic under the approximation of large volume compactification. The absence of constraint on the compactified volume for the meta-stable de-Sitter vacua in this model leads to a controllable α' correction. We find that the median Λ50% is exponentially suppressed by the compactified volume and the probability distribution function of Λ diverges as Λ approaches 0+. We then study the large volume scenario model and show that the scale of gravitino mass can be splitted from that of the cosmological constant. The probability distribution of Λ in this model where SUSY can be broken or remain unbroken peaks at Λ = 0- but anti de-Sitter vacua is generic in this model in the absence of fine tuned uplifting.

▼ The AdS/CFT correspondence conjectures the duality
between type IIB
supergravity on AdS
5 x S
5 and N = 4 super
Yang-Mills theory. Mass deformations of N = 4 super Yang-Mills
theory drive renormalization group (RG) flows. Holographic RG flows
are described by domain wall solutions interpolating between AdS
5
geometries at critical points of N = 8 gauged
supergravity in five
dimensions. In this thesis we study two directions of
generalizations of holographic RG flows. ❧ First, motivated by the
Janus solutions, we study holographic RG flows with dilaton and
axion fields. To be specific, we consider the SU(3)-invariant flow
with dilaton and axion fields, and discover the known
supersymmetric Janus solution in five dimensions. Then, by
employing the lift ansatz, we uplift the supersymmetric Janus
solution of the SU(3)-invariant truncation with dilaton and axion
fields to a solution of type IIB
supergravity. We identify the
uplifted solution to be one of the known supersymmetric Janus
solution in type IIB
supergravity. Furthermore, we consider the
SU(2)xU(1)-invariant N = 2 and N = 1 supersymmetric flows with
dilaton and axion fields. ❧ Second, motivated by the development in
AdS/CMT, we study holographic RG flows with gauge fields. We
consider the SU(3)-invariant flow with electric potentials or
magnetic fields, and find first-order systems of flow equations for
each case.

▼ This dissertation begins with a review of Calabi-Yau manifolds and their moduli spaces, flux compactification largely tailored to the case of type IIb supergravity, and Coleman-De Luccia vacuum decay. The three chapters that follow present the results of novel research conducted as a graduate student.
Our first project is concerned with bubble collisions in single scalar field theories with multiple vacua. Lorentz boosted solitons traveling in one spatial dimension are used as a proxy to the colliding 3-dimensional spherical bubble walls. Recent work found that at sufficiently high impact velocities collisions between such bubble vacua are governed by "free passage" dynamics in which field interactions can be ignored during the collision, providing a systematic process for populating local minima without quantum nucleation.
We focus on the time period that follows the bubble collision and provide evidence that, for certain potentials, interactions can drive significant deviations from the free passage bubble profile, thwarting the production of a new patch with different field value. However, for simple polynomial potentials a fine-tuning of vacuum locations is required to reverse the free passage kick enough that the field in the collision region returns to the original bubble vacuum. Hence we deem classical transitions mediated by free passage robust.
Our second project continues with soliton collisions in the limit of relativistic impact velocity, but with the new feature of nontrivial field space curvature. We establish a simple geometrical interpretation of such collisions in terms of a double family of field profiles whose tangent vector fields stand in mutual parallel transport. This provides a generalization of the well-known limit in flat field space (free passage). We investigate the limits of this approximation and illustrate our analytical results with numerical simulations.
In our third and final project we investigate the distribution of field theories that arise from the low energy limit of flux vacua built on type IIb string theory compactified on the mirror quintic. For a large collection of these models, we numerically determine the distribution of Taylor coefficients in a polynomial expansion of each model's scalar potential to fourth order. We provide an analytic explanation of the proncounced hierarchies exhibited by the random sample of masses and couplings generated numerically. The analytic argument is based on the structure of masses in no scale supergravity and the divergence of the Yukawa coupling at the conifold point in the moduli space of the mirror quintic. Our results cast the superpotential vev as a random element whose capacity to cloud structure vanishes as the conifold is approached.

▼ Finding a quantum theory of gravity and unifying our description of the fundamental forces in the universe has been a long-standing goal of the physics community for the last several decades. Black holes provide a setting where both gravitational and quantum effects are important, and as such they are valuable in probing how such a theory of quantum gravity must behave; any quantum description of a black hole should be consistent with its macroscopic (low-energy) description in general relativity.
The only known examples where the microscopic details of a black hole are understood come from string theory and are heavily reliant on supersymmetry. Little is known about how to extend these descriptions to more realistic, non-supersymmetric settings. In this thesis, we make progress on this front by undergoing a careful exploration of non-supersymmetric black holes in theories of
supergravity. In particular, we show how generic Kerr-Newman black holes, when interpreted as solutions to N=2
supergravity, exhibit a surprising amount of universality in their behavior that points to a great deal of simplicity in their underlying quantum description.
In the first part of this thesis, we embed arbitrary Kerr-Newman black holes into N=2
supergravity. We then study the quantum fluctuations around these backgrounds and compute their contributions to the black hole entropy. We find that these quantum corrections are protected by a topological quantity and are thus invariant under arbitrary deformations of the black hole away from the BPS limit. The logarithmic corrections to the Bekenstein-Hawking entropy are thus universal and independent of black hole parameters for these black holes.
In the second part of this thesis, we study minimal
supergravity with higher derivative corrections and show that Kerr-Newman black holes can be consistently embedded into such theories with no modifications required to the geometry. Moreover, we show that these black holes are continuously connected to a BPS geometry. We also find that the entropy of these black holes is a topological invariant and thus insensitive to whether or not the black hole is a BPS state.
In the final part of this thesis, we explore the symmetries of off-shell N=2
supergravity and the corresponding constraints these symmetries impose on the theory. In particular, we show that the topological nature of our results follows directly from symplectic duality and supersymmetry. Moreover, these constraints persist even for black hole solutions that break the supersymmetry of the theory. These results establish a previously-unknown level of structure in the underlying microscopic description of these black holes.

▼ Supersymmetry has played an important role in theoretical physics for the last thirty years. In the quest for unification of the fundamental interactions, supersymmetry provides the framework that links two seemingly unrelated kinds of particles, namely bosons and fermions. Supersymmetry is a vital ingredient for the construction of string theories, which in turn are the building blocks of a conceived fundamental theory of nature, so-called M-theory.
The fundamental degrees of freedom of M-theory are not yet known. M-theory is only defined as a theory that, in certain limits, coincides with the known string theories or with supergravity theories. In the limit of low-energy interactions, i.e. at energies much smaller than the Planck mass M-theory is described in terms of supersymmetric gauge theories and supergravity theories. In order to find the correct description of M-theory, it is vital to further explore new features of the effective low-energy theories. In this thesis, we study two different extensions of supergravity theories in an attempt to gain new insights into the nature of M-theory. One possibility for extending a supersymmetric field theory is to couple the original, massless theory to massive BPS multiplets. The second possibility is to construct a gauged supergravity theory by extending the abelian gauge symmetry of a supergravity theory to a non-abelian symmetry.

▼ Supersymmetry has played an important role in theoretical physics for the last thirty years. In the quest for unification of the fundamental interactions, supersymmetry provides the framework that links two seemingly unrelated kinds of particles, namely bosons and fermions. Supersymmetry is a vital ingredient for the construction of string theories, which in turn are the building blocks of a conceived fundamental theory of nature, so-called M-theory.
The fundamental degrees of freedom of M-theory are not yet known. M-theory is only defined as a theory that, in certain limits, coincides with the known string theories or with supergravity theories. In the limit of low-energy interactions, i.e. at energies much smaller than the Planck mass M-theory is described in terms of supersymmetric gauge theories and supergravity theories. In order to find the correct description of M-theory, it is vital to further explore new features of the effective low-energy theories. In this thesis, we study two different extensions of supergravity theories in an attempt to gain new insights into the nature of M-theory. One possibility for extending a supersymmetric field theory is to couple the original, massless theory to massive BPS multiplets. The second possibility is to construct a gauged supergravity theory by extending the abelian gauge symmetry of a supergravity theory to a non-abelian symmetry.

▼ Dans cette thèse, nous présentons des avancements récents en Théorie des Champs Doubles (TCD) et Théories des Champs Exceptionnels (TCE). Ces théories ont la particularité d’être des reformulations de supergravité dans lesquelles les symétries de dualité sont explicites avant toute réduction dimensionnelle. Ces reformulations se basent sur la définition d’un espace-temps étendu qui géométrise le groupe de T-dualité en TCD et les groupes exceptionnels de U-dualité en TCE. Tous les champs de cet espace sont soumis à une contrainte de section qui restreint leur dépendance en coordonnées. Il existe plusieurs solutions à la contrainte de section, qui correspondent donc à des théories différentes. Dans ce sens, le formalisme des théories des champs étendues amène à une unification de ces théories. De plus, grâce à un outil spécifique aux théories des champs étendues, l’ansatz de Scherk-Schwarz généralisé, il est possible de réécrire les ansatz compliqué de type Kaluza-Klein en supergravité sous une forme élégante et compacte: un produit matriciel en dimensions supérieures. Ici, nous présentons plusieurs exemples de l’efficacité de l’ansatz de Scherk-Schwarz généralisé. En particulier, nous prouvons deux conjectures concernant les troncations cohérentes: la réduction dite “de Pauli” de la corde bosonique ainsi que la supergravité de type IIB sur AdS5 x S5. La dernière application de cet ansatz concerne la théorie de type IIB généralisée, apparue récemment dans l’étude des système intégrables, et son plongement dans la TCE E6(6). Enfin, nous présentons la complétion supersymétrique de la TCE E8(8) bosonique.
In this thesis, recent developments in Double Field Theory (DFT) and Exceptional Field Theory (EFT) are presented. They are reformulation of supergravity in which duality symmetries are made manifest before dimensional reduction. This is achieved through the definition of an extended spacetime that “geometrises” the T-duality group O(d,d) in DFT and exceptional U-duality groups in EFT. All functions on this extended space are subject to a covariant `section constraint', whose solutions then restrict the coordinates dependency of the fields. There exist different solutions to the section constraint that correspond to different theories. In this sense, different theories are unified within the formalism of extended field theories. Moreover, extended field theories possess a powerful tool to study compactifications: the generalised Scherk-Schwarz ansatz.Here, we present several examples of the effectiveness of the generalised Scherk-Schwarz ansatz. In particular, we proved two conjectures regarding consistent truncations: the so-called Pauli reduction of the bosonic string on group manifolds and type IIB supergravity on AdS5 x S5. Another application is presented on the embedding of generalised type IIB within the E6(6) EFT, which recently appeared in the study of integrable systems.Finally, we present the supersymmetric completion of the bosonic E8(8) EFT.

▼ In this thesis, we examine in detail the notion of black hole entropy in Quantum Field Theories, with a specific focus on supersymmetric black holes and the perturbative and non-perturbative quantum corrections to the classical area-law of Bekenstein-Hawking, where the latter stipulates that the thermodynamic entropy of a black hole is proportional to the surface area of its event horizon. To examine such corrections, we employ the formalism of Sen's Quantum Entropy Function where the complete quantum entropy of a supersymmetric black hole in theories of
Supergravity is defined as a path-integral in the near-horizon region of the black hole. Evaluation of this path-integral can then be conducted exactly using localization computation techniques. Such techniques reduce the evaluation of the infinite dimensional path-integral to the evaluation of a classical, finite-dimensional integral over the so-called localizing manifold, and a one-loop correction stemming from quantum field fluctuations orthogonal to this localizing manifold. Due to the exactness of the localization argument, the results obtained in this manner are therefore formally expected to re-sum all perturbative and non-perturbative corrections to the classical area-law, and thus connect to string-theoretic predictions, where supersymmetric black holes can be described as D-branes interacting quantum mechanically (following the original insight of Strominger and Vafa). We investigate such connections in detail for specific supersymmetric black holes in the hopes of strengthening a Boltzmann-type interpretation of their thermodynamic entropy as arising from the degeneracies of the microscopic gravitational constituents (the D-branes). We find that this picture holds very precisely for two types of black holes preserving four real supercharges in both four-dimensional N=8 (maximally supersymmetric) and N=4 (half-maximally supersymmetric) string theories and supergravities. From a broader point of view, such results can be interpreted as providing important examples where
supergravity theories encode the complete low-energy dynamics of string theories and provide a consistent effective picture. Some interesting connections to the mathematical theory of modular forms and mock modular forms are also exhibited.

▼ In this dissertation, we investigatethe supersymmetric completion of curvature squared invariants in five and six dimensionsas well as the construction of off-shell Poincar?e supergravities and their matter couplings.
We use superconformal calculus in fiveand six dimensions, which are an off- shell formalisms. In fivedimensions,there are twoinequivalentWeyl multiplets: the standard Weyl multiplet and the dilaton Weyl multiplet.The main difference betweenthese twoWeyl multiplets is thatthe dilaton Weyl multipletcontains a graviphoton in its field content whereas the standard Weyl multiplet does not.A
supergravity theory based on the standard Weyl multiplet requires coupling to an external vector multiplet. In five dimensions,we construct two new formulations for 2-derivative off-shell Poincar?e
supergravity theories and present the internally gauged models.
We also construct supersymmetric completions of all curvature squared terms in five dimensional
supergravity with eight supercharges.Adopting the dilaton Weyl multiplet, we construct a Weyl squared invariant, the supersymmetric combination of Gauss-Bonnet combination and the Ricci scalar squared invariant as well as all vector multiplets coupled curvature squared invariants. Since the minimal off-shell supersymmetric Riemann tensor squared invariant has been obtained before, both the minimal off-shell and the vector multiplets coupled curvature squared invariants in the dilation Weyl multiplet are complete. We also constructedan off-shell Ricci scalar squared invariant utilizing the standard Weyl multiplet.The supersymmetric Ricci scalar squared in the standard Weyl multiplet is coupled to n number of vector multiplets by construction, and it deforms the very special geometry. We found that in the supersymmetric AdS5 vacuum, the very special geometry defined on the moduli space is modified in a simple way. We study the vacuum solutions with AdS2 ? S3 and AdS3 ? S2 structures. We also analyze the spectrum around a maximally supersymmetric Minkowski5, and study the magnetic string and electric black hole.
Finally, we generalize our procedure for the construction of an off-shell Ricci scalar squared invariant in five dimensions to N = (1, 0), D = 6
supergravity.

▼ An explanation for the entropy of black holes has been an outstanding problem in recent decades. A special case where this is possible is that of extremal black holes in N=2
supergravity in four and five dimensions. The best developed case is for black holes preserving some supersymmetry (BPS), which are well understood in the context of the lowest order two derivative action. For ungauged theories, one can use the experience gained from this example to study the effect of higher order corrections on BPS solutions or to construct nonsupersymmetric black holes. We first present a detailed discussion of the four derivative terms allowed by N=2 supersymmetry in four and five dimensions respectively. Each of these invariants is parametrised by an arbitrary function, which can be fixed when one considers the embedding in a microscopic theory, such as string theory. We present a detailed investigation of the possible N=2 backgrounds, described in a unified way for both black holes and rings. Restricting to the class of theories obtained by string theoretic models, we connect to known microscopic constructions of black holes. The end result is a successful match of the entropy to the string theory counting for black rings and for large black holes. Issues remain with small black holes in the five-dimensional case. Beyond supersymmetric solutions, we discuss some recent results on the construction of non-BPS solutions in N=2 theories, emphasising the description in terms of first order equations and the attractor mechanism. We introduce a special class of five-dimensional solutions which are supersymmetric on local patches of spacetime, but nevertheless completely break supersymmetry globally. The new solutions obtained turn out to allow for a number of features that are present in generic extremal solutions, but forbidden in the supersymmetric case. Based on this fact, we then go on to propose a framework for constructing more general extremal solutions, including rotating black holes.

▼ In N = 2 conformal supergravity in four spacetime dimensions, there exist o -shell supermultiplets with intrinsic central charge, including the Fayet-Sohnius hypermultiplet, the vector-tensor (VT) multiplet and the linear multiplet. Here we construct superform formulations for such multiplets and their variants. To begin with, we review superspace formulations for four-dimensional N = 2 conformal supergravity. We consider models involving both vector and tensor multiplets coupled to supergravity and demonstrate explicitly how component actions may be e ciently obtained with the use of superspace techniques. We introduce the VT multiplets in N = 2 Poincare and AdS supersymmetry. In particular, we discuss the linear and nonlinear VT multiplets. A general setting for N = 2 AdS supersymmetric theories with central charge is presented. A supersymmetric action principle is given in N = 2 AdS superspace and then reformulated in terms of N = 1 super- elds. A proof is presented of the nonexistence of a linear VT multiplet in N = 2 AdS supersymmetry. For the nonlinear VT multiplet, we derive consistent super eld constraints in the presence of any number of N = 2 Yang-Mills vector multiplets, give the supersymmetric action and elaborate on the N = 1 super eld and component descriptions of the theory. In supergravity, we present superform formulations for two versions of VT multiplets and their Chern-Simons couplings. One of them is the standard VT multiplet with the central charge gauged by a vector multiplet. The other is the variant VT multiplet with the property that its own one-form gauges the central charge.
The construction of supersymmetric actions for the standard VT multiplet is performed with the use of the linear multiplet. We provide a superform formulation for the linear multiplet and derive the corresponding action functional using the ectoplasm method. We introduce a deformed linear multiplet and a supersymmetric action associated with it. The novel feature of this multiplet is that it corresponds to the case where the central charge is gauged using a one-form potential that is not annihilated by the central charge (unlike the standard N = 2 vector multiplet). This modi cation is required for the construction of the action for the variant VT multiplet. Finally, we show that our superspace description leads to an e cient means of deriving component actions in supergravity. The entire action including all fermionic terms is derived for the nonlinear VT multiplet. This extends the results of de Wit et al. in hep-th/9710212, where only the bosonic sector appeared. Finally, the bosonic sector of the action for the variant VT multiplet is given.

▼ Stabilized string compactifications give rise to effective four-dimensional supergravities at energies below the compactification scale, and in this thesis, we investigate how these theories may be constrained by physical observables from particle physics and cosmology. A number of physically well-motivated scenarios such as cosmic inflation, intermediate-scale supersymmetry breaking, and a particular mechanism for baryogenesis, all rely on the form of the nonrenormalizable, Planck-mass suppressed operators in the Lagrangian, which can be computed only in a quantum theory of gravity. With this motivation, we investigate supersymmetry breaking in stabilized compactifications of type IIB string theory, and find that experimental constraints from flavor physics impose severe restrictions on certain interesting compactification scenarios. Moreover, we point out that the Affleck-Dine scenario is incompatible with some models of string inflation, e.g. brane inflation in warped throats, and we show that versions of Affleck-Dine baryogenesis with non-trivial field dynamics during observable inflation induce features in the spectrum of the cosmic microwave background radiation, which may be observable by upcoming satellite experiments, such as Planck. Furthermore, there is compelling cosmological evidence for a 'dark energy' currently dominating the energy density of the universe, but accommodating this fact by direct constructions of de Sitter string vacua has proved challenging. Here, we use random matrix theory to show that in super- gravities with many scalar fields, an exponentially small fraction of the de Sitter critical points are metastable vacua. This result significantly affects the counting of de Sitter vacua in the string landscape.

▼ E bem conhecido como descrever as teor´ıas de Super Yang-Mills (SYM) ´ em D = 10 dimens˜oes e Supergravidade (SG) em D = 11 dimens˜oes no superespa¸co e via seus campos componentes. No entanto, uma nova vers˜ao desses modelos foi formulada nos finais da d´ecada de 2000, quando Martin Cederwall usando o formalismo de supercampo de espinor puro conseguiu construir uma pure spinor a¸c˜ao, que a diferen¸ca das anteriores abordagens, esta n˜ao precisa de impor constraints a m˜ao, proporciona uma descri¸c˜ao completa de cada modelo (no sentido do formalismo BV) e as equa¸c˜oes do movimento obtidas a partir do respectivo principio de a¸c˜ao s˜ao supersim´etricas. Neste trabalho iremos explicar toda a base necess´aria para entender a constru¸c˜ao de tal formalismo. Para esse prop´osito, come¸caremos estudando a teoria SYM (abeliana) em D = 10 em suas formula¸c˜oes em componentes e no superespa¸co. Usaremos a a¸c˜ao da formula¸c˜ao on-shell para quantizar a teoria via o formalismo de Batalin-Vilkovisky (BV). Seguiremos para SG em D = 11 e estudaremos suas formula¸c˜oes em componentes e no superespa¸co. Ent˜ao iremos mostrar que podemos obter o mesmo espectro f´ısico de SYM em D = 10 (SG em D = 11) estudando a superpart´ıcula em D = 10 (D = 11) na calibre do cone de luz. De forma a ter uma quantiza¸c˜ao covariante desses modelos, introduziremos a superpart´ıcula de espinor puro em D = 10 (D = 11), a qual possui o operador BRST usual de espinor puro (Q = λD). Verificar-se-´a que a cohomologia desse operador coincidir´a com a teoria SYM em D=10 (SG em D=11) linearizada depois de ser quantizada via o formalismo BV. Esse resultado introduzir´a naturalmente a ideia de construir a¸c˜oes usando um supercampo de espinor puro. Finalmente, explicaremos como o formalismo de supercampo de espinor puro surge nesse contexto e como podemos us´a-lo para construir a¸c˜oes manifestamente supersim´etricas para SYM em D=10 e SG em D=11.
It is well known how to describe the D = 10 (SYM) Super Yang-Mills and D = 11 (SG) Supergravity theories on superspace and by component fields. However, a new version of these models was formulated in the late 2000, when Martin Cederwall using the pure spinor superfield formalism achieved to construct a pure spinor action for these theories, which unlike the previously mentioned approaches, this does not require to impose any constraint by hand, provides a full description of each model (in the BV sense) and the equations of motion coming from the corresponding action principle are supersymmetric. In this work we will explain all the background required to understand the construction of this action. For this purpose, we will start with the D=10 (abelian) SYM theory in its component and superspace formulations. We will use the action of the on-shell formulation to quantize the theory via the Batalin-Vilkovisky framework. We will move to D=11 supergravity and study its component and superspace formulations. Then we will show that we can obtain the same physical spectrum of D = 10 SYM (D = 11 SG) by studying the D…

▼ Five-dimensional N=2 Yang-Mills-Einstein supergravity
and its couplings to hyper and tensor multiplets are considered on
an orbifold spacetime of the form M4 X S1/Gamma, where Gamma
is the discrete group Z2 or Z2XZ2. As is well known in
such cases, supersymmetry is broken to N=1 on the orbifold fixed
planes, and chiral 4D theories can be obtained from bulk
hypermultiplets (or from the coupling of fixed-plane supported
fields). Five-dimensional gauge symmetries are broken by boundary
conditions for the fields, which are equivalent to some set of
Gamma-parity assignments in the orbifold theory, allowing for
arbitrary rank reduction. Furthermore, Wilson lines looping from
one boundary to the other can break bulk gauge groups, or give rise
to vacuum expectation values for scalars on the boundaries, which
can result in spontaneous breaking of boundary gauge groups. The
broken gauge symmetries do not survive as global symmetries of the
low energy theories below the compactification scale due to 4D
minimal couplings to gauge fields. Axionic fields are a generic
feature, just as in any compactification of M-theory (or string
theory for that matter), and we exhibit the form of this field and
its role as the QCD axion, capable of resolving the strong-CP
problem. The main motivation for the orbifold theories here is
taken to be orbifold-GUTs, wherein a unified gauge group is sought
in higher dimensions while allowing the orbifold reduction to
handle problems such as rapid proton decay, exotic matter, mass
hierarchies, etc. To that end, we discuss the allowable minimal
SU(5), SO(10) and E6 GUT theories with all fields living in five
dimensions. It is argued that, within the class of homogeneous
quaternionic scalar manifolds characterizing the hypermultiplet
couplings in 5D, supergravity admits a restricted set of theories
that yield minimal phenomenological field content. In addition,
non-compact gaugings are a novel feature of supergravity theories,
and in particular we consider the example of an SU(5,1) YMESGT in
which all of the fields of the theory are connected by local (susy
and gauge) transformations that are symmetries of the Lagrangian.
Such non-compact gaugings allow a novel type of gauge-Higgs
unification in higher dimensions. The possibility of
boundary-localized fields is considered only via anomaly arguments.
In particular, the theories with a 5D Chern-Simons form in the
Lagrangian will give rise to anomaly inflow classically (which is
compensated globally in the S1/Z2 case). However,
compensation locally requires the quantum theory to have a chiral
anomaly on the boundary, which can arise if there is an appropriate
bulk fermionic field content, or otherwise by the addition of
appropriate boundary-supported fermionic fields with minimal
coupling to the gauge fields propagating there. Some comments are
made regarding the phenomenological features of the models, such as
the Yukawa couplings and scalar potentials, which depend on the
size of the fifth dimension as well as the scalar vacuum.…

▼ Equations of motion of eleven dimensional supergravity
compactified to d dimensions on (11-d)-torus have a hidden
non-compact global symmetry group mathrm{E}11-d(11-d), being
examples of U-duality groups. U-duality groups are conjectured to
be broken to their discrete subgroups mathrm{E}11-d(11-d) left(
ℤ ight) in the non-perturbatve M-theory. In this thesis we
study algebraic structures and unitary realizations of U-duality
groups, in particular those arising from Maxwell-Einstein
supergravity (MESGT) theories in d=5, 4, 3 dimensions. These
algebraic structures and their related symmetry groups arise also
in the study of generalized space-times defined by Jordan algebras
and related algebraic constructs. After reviewing the previous work
on the Lorentz groups and conformal groups of spacetimes defined by
Jordan algebras we study their quasi-conformal groups. In
particular we give the geometric realization of these
quasi-conformal groups in a basis covariant with respect to their
generalized Lorentz groups. Minimal realization of U-duality groups
associated with d=3 supergravities is constructed as an extension
of conformal quantum mechanics using ideas and methods pioneered by
G"unaydin, Koepsell and Nicolai. Minimal unitary representations of
such U-duality groups are presented ellucidating connection with
alternative construction of minimal representations by Kazhdan,
Pioline and Waldron.

▼ La supersymétrie représente le cadre théorique phare en physique des particules pour prendre la relève du modèle standard. Cependant, en tant que cadre général, il dispose de beaucoup de liberté dans sa mise en oeuvre, notamment au niveau des modèles de brisure. Le travail principal de cette thèse consiste à tenter de réduire l'espace des paramètres par des considérations théoriques, en trouvant un sous-espace réduit dans les modèles de brisure par médiation gravitationnelle, en utilisant les méthodes de minimisation du potentiel effectif développé dans les scénarios dits no-scale.
Supersymmetry is the most preferred theoretical framework that could replace and complete the standard model of particle physics. However it is hard to distinguish clearly between all the possible models allowed.During this thesis, we tried to reduce the arbitrariness in the choice of some parameters in supergravity breaking models, by looking at minimisation methods introduced in no-scale supergravity scenarios.

▼ In this thesis we study gauge/gravity duals in the 5d/6d AdS/CFT correspondence. We start with field theories defined on squashed five-spheres with SU(3) × U(1) symmetry. These five-sphere backgrounds are continuously connected to the round sphere. We find a one-parameter family of 3/4 BPS deformations and a two-parameter family of (generically) 1/4 BPS deformations. The gravity duals are constructed in Euclidean Romans F(4) gauged supergravity in six dimensions, and uplift to massive type IIA supergravity. We holographically renormalize the Romans theory, and use our general result to compute the renormalized on-shell actions for the solutions. The results agree perfectly with the large N limit of the dual gauge theory partition function, which we compute using large N matrix model techniques. In addition we compute BPS Wilson loops in these backgrounds, both in supergravity and in the large N matrix model, again finding precise agreement. We conjecture a general formula for the partition function on any five-sphere background, which for fixed gauge theory depends only on a certain supersymmetric Killing vector. We then proceed to study Euclidean Romans supergravity in six dimensions with a non-trivial Abelian R-symmetry gauge field. We show that supersymmetric solutions are in one-to-one correspondence with solutions to a set of differential constraints on an SU(2) structure. As an application of our results we (i) show that this structure reduces at a conformal boundary to the five-dimensional rigid supersymmetric geometry previously studied, (ii) find a general expression for the holographic dual of the VEV of a BPS Wilson loop, matching an exact field theory computation, (iii) construct holographic duals to squashed Sasaki-Einstein backgrounds, again matching to a field theory computation, and (iv) find new analytic solutions to the squashed five-sphere background. We also analyse the classification of gravity duals with zero B-field.
