▼ Many Beyond Standard Model theories predict particles that couple strongly to top/anti-top quark pairs. This makes tt(bar) a promising signature for new physics searches. The analysis presented in this dissertation uses 20.3 fb⁻¹ of √s = 8 TeV pp collision data from the ATLAS experiment to search for evidence of new physics in the single-lepton plus jets tt(bar) decay channel. This is done by requiring one electron or muon, large missing transverse momentum and additional hadronic jets. The tt(bar) system is reconstructed using techniques optimized for either resolved or boosted event topologies. The results of the analysis are used to set upper limits on the production cross-section times branching ratio for heavy
resonances decaying to tt(bar). These limits are interpreted in the context of several benchmark models including the leptophobic topcolor Z', the Randall-Sundrum Kaluza-Klein gluon (gKK), the Randall-Sundrum Kaluza-Klein graviton (GKK) and a spin-0 scalar particle.

▼ This thesis contains a detailed study of the rates of wave decay for scattering by thin barriers. Thin barriers are systems in which, except for a narrow region, waves do not interact. This type of behavior is observed in physical systems including concert halls and quantum corrals. A quantum corral is constructed by configuring individual atoms or molecules to form a barrier which partially confines electrons to its interior. Here, the atoms produce a potential which plays the role of the thin barrier. In the setting of concert halls, the walls play the role of the barrier and produce partial confinement of sound waves. Rather than studying systems with a finite width interaction region, we imagine that the interaction region is reduced to a single hypersurface in R^d by taking a limit of barriers whose width is decreasing and intensity is increasing.Specifically, we are interested in wave equations with delta and delta' potentials on a hypersurface. These operators are used as models for leaky quantum graphs and quantum corrals.

This works presents the first measurements of three double-polarization observables for the &gamma p &rarr K+ &Lambda reaction: E (beam-target asymmetry), Lx' and Lz' (target-recoil asymmetries). Each of these measurements required the longitudinal polarization of target protons. To that end, a longitudinally polarized frozen-spin butanol target was constructed for use in the Thomas Jefferson National Accelerator Facility's Hall B. The data presented in this analysis were taken during the g9a run period from November 2007 - February 2008 using the aforementioned target and a circularly polarized photon beam in the energy range of 0.5 - 2.4 GeV . The motivation for this experiment was to extend the set of measured observables describing the reaction channel in order to aid in the search for missing baryon resonances. The complete set of polarization observables can be used to perform a model-independent partial wave analysis (PWA) of the reaction channel and extract resonant contributions to the cross section. Consistency checks with previously measured polarization observables were also performed by extracting the &Lambda recoil polarization and the beam-recoil asymmetries Cx' and Cz' . The recoil polarization P extracted from g9a data is in good agreement with previous data. On the other hand, some major discrepancies are found between the g9a results and previous data for the beam-recoil transfer Cx' and Cz'. The statistics generated for K+ &Lambda were insufficient to adequately resolve between models, although better agreement with the Mart-Bennhold model which includes the missing D13(1960) resonance was evident in much of the data. Nonetheless, little evidence of resonant structure appears in the smoothly varying measurements of E and the target-recoil tranfer Lx' and Lz' are frequently consistent with a flat asymmetry or none at all. Identification of missing resonances from individual observable measurements is unlikely. Instead, these new measurements will serve to further constrain parameters for the full PWA of &gamma p &rar K+ &Lambda.

Ova teza predstavlja teorijsku analizu različitih
koherentnih efekata u laserski pobuđivanim Ramanovim rezonancama u
sistemima sa više nivoa u atomima rubidijuma. Proučavani koherentni
efekti uključuju elektromagnet- ski indukovanu transparenciju
(EIT), elektromagnetski indukovanu apsor- pciju (EIA) i Štarkovski
brzi adijabatski prelaz (engl. SCRAP). EIT i EIA rezonance su
ispitivane u Hanle konfiguraciji u vakuumskim ćelijama para
rubidijuma detaljnim teorijskim modeliranjem odgovarajućih
realističnih sistema. Razvijeni numerički model je pokazao odlično
slaganje sa odgovarajućim eksperimentalnim rezultatima i omogućio
njihovo uspešno objašnjenje. Dodatno, postojeća teorija SCRAP-a u
sistemima sa dva i tri nivoa je proširena na slučajeve dva i tri
nivoa sa proizvoljnim brojem degenerisanih podnivoa. Vakuumske
ćelije para alkalnih metala su često korišćene u kvantnoj optici
prilikom istraživanja koherentnih pojava u interakciji lasera sa
atomima. Jedna od osnovnih osobina laserskog zračenja koja utiče na
koherentnu evoluciju atoma je njegov lokalni intenzitet. Uopšteno
gledano, koherentni efekti zavise nelinearno od intenziteta lasera.
Neposredna posledica toga je da profil intenziteta laserskog snopa
mora uticati na koherentnu atomsku evoluciju. Štaviše, različiti
delovi jednog istog laserskog snopa trebalo bi da različito
doprinose koherentnim efektima...

▼ Recent advances in theory and experiment have renewed efforts in the phenomenological under-standing of scattering for hadronic systems. Calculations in lattice QCD have shown that
resonances can be extracted from the finite volume spectrum. These observables require analytic models to continue the amplitude to the complex energy plane to determine the infinite volume hadron spectrum. The forefront of this research is determining scattering observables for three particles from the finite volume spectra. We present an analytic representation for the elastic three-body scattering amplitude, which can be effectively used in lattice QCD calculations of amplitudes. Aspects of its analytic properties are discussed, specifically the one-particle exchange effects and triangle singularities, which are possible explanations for the many observed exotic hadrons.

▼ This thesis reports on experimental observation of heteronuclear Feshbach
resonances between ultracold alkaline-earth-like Yb and alkali Li atoms, revealing methods for experimental control of heteronuclear scattering properties and strategies for coherent production of YbLi molecules. Optical Feshbach
resonances are observed between Yb-174 and Li-6 through photoassociation (PA) spectroscopy. Two-photon PA spectroscopy of a series of the least-bound vibrational states in the YbLi electronic ground state provides an accurate description of the long-range interatomic potential and an accurate value of the s-wave scattering lengths between Yb and Li. A dark atom-molecule superposition state is created by optically dressing pairs of colliding atoms within an optically trapped bulk mixture and the feasibility of using such a state for coherent molecule production through stimulated Raman adiabatic passage is discussed. Magnetic Feshbach
resonances (MFRs) between Yb-173 and Li-6 are observed. In the combination of closed-shell Yb and open-shell Li, MFRs are shown to stem from short-ranged hyperfine coupling between the unpaired Li electron spin and the Yb-173 nuclear spin, as demonstrated by analysis of Feshbach spectroscopy on ultracold mixtures in which both species are fully spin polarized. This work identifies two pathways for the coherent production of paramagnetic, polar molecules from a mixture of trapped Yb and Li: manipulation of either an optical or magnetic Feshbach resonance.

▼ Waveguides in Euclidian space are piecewise path connected subsets of R^n that can be written as the union of a compact domain with boundary and their cylindrical ends. The compact and non-compact parts share a common boundary. This boundary is assumed to be Lipschitz, piecewise smooth and piecewise path connected. The ends can be thought of as the cartesian product of the boundary with the positive real half-line. A notable feature of Euclidian waveguides is that the scattering matrix admits a meromorphic continuation to a certain Riemann surface with a countably infinite number of leaves [2], which we will describe in detail and deal with. In order to construct this meromorphic continuation, one usually first constructs a meromorphic continuation of the resolvent for the Laplace operator. In order to do this, we will use a well known glueing construction (see for example [5]), which we adapt to waveguides. The construction makes use of the meromorphic Fredholm theorem and the fact that the resolvent for the Neumann Laplace operator on the ends of the waveguide can be easily computed as an integral kernel. The resolvent can then be used to construct generalised eigenfunctions and, from them, the scattering matrix. Being in possession of the scattering matrix allows us to calculate resonances; poles of the scattering matrix. We are able to do this using a combination of numerical contour integration and Newton s method.

▼ Optically resonant nanostructures have been
incorporated into a variety of devices
used in a number of
different fields. In this thesis, we explore optically resonant
nanostructures in two forms.
First we investigate a relatively new
material, gallium implanted silicon (Si:Ga).
We cover the
fabrication process and experimentally find the optical properties
as a function of both dose and wavelength. We then use the
properties of this
new material to create suspended arrays of
Si:Ga nanowires, and determine their
optical characteristics.
In
the second part of this thesis, we use more conventional materials
and fabrication
procedures to investigate the phase effects of
guided mode resonators. We
look at the spectral phase effects for
a grating coupled silicon-on-insulator based
guided mode
resonator. We also look the angular phase effects of a surface
plasmon
polariton based guided mode resonator, comparing
experimental results to
theory calculated with rigorous coupled
wave analysis for both cases. In addition,
the guided mode
resonance is modeled as a Fano resonance to gain insight into
the
functional form of the phase. Knowing the phase response of guided
mode
resonances may allow the creation of guided mode resonance
based devices with
higher sensitivity than traditional reflectance
based devices.

▼ This Master’s dissertation focuses on engineering artificial nanostructures, namely, arrays of metamolecules on a substrate (metasurfaces), with the goal to achieve the desired linear and nonlinear optical responses. Specifically,
a simple analytical model capable of predicting optical nonlinearity of an
individual metamolecule has been developed. The model allows one to estimate the nonlinear optical response (linear polarizability and nonlinear hyperpolarizabilities) of a metamolecule based on the knowledge of its shape,
dimensions, and material. In addition, a new experimental approach to measure hyperpolarizability has also been investigated. As another research effort, a 2D plasmonic metasurface with the collective behaviour of the metamolecules known as hybrid plasmonic-Fabry-Perot cavity and surface lattice resonances was designed, fabricated and optically characterized. We experimentally discovered a novel way of coupling the microcavity resonances and the diffraction orders of the plasmonic metamolecule arrays with the low-quality plasmon resonance to generate multiple sharp resonances with the higher quality factors. Finally, we experimentally observed and
demonstrated a record ultra-high-Q surface lattice resonance from a plasmonic metasurface. These novel results can be used to render highly efficient
nonlinear optical responses relying on high optical field localization, and can
serve as the stepping stone towards achieving practical artificial nanophotonic devices with tailored linear and nonlinear optical responses.

▼ The study of nanostructured artificial media for optics has
expanded rapidly over the last few decades, coupled with
improvements of fabrication technology that have enabled
investigation of previously unrealisable optical scattering
systems. Such development is complemented by renewed impetus to
understand the physics of optical scattering from
complex subwavelength geometry and nanoparticle systems. Here I
investigate speci
cally the optical properties of closely packed
arrangements of nanoparticles, known as nanoparticle oligomers,
which provide an intuitive platform for analytical and numerical
study on the formation and interplay of collective resonances. I
consider both plasmonic nanoparticles, and also
high-refractive-index dielectric nanoparticles that support
Mie-type electric and magnetic dipole resonances. Specifi c
outcomes of this study are listed as follows. (i) A new model is
presented for optical Fano resonances, which is based on
interference between nonorthogonal eigenmodes of the associated
scattering object. This is demonstrated to correctly describe
Fano resonances in both plasmonic and high-refractive-index
dielectric
nanoparticle oligomers; it also revealed capacity for two-channel
Fano interference in the magnetic dipolar response from the
dielectric oligomers. (ii) Polarisation-independent scattering
and absorption losses are shown to be enforced by n-fold discrete
rotational symmetry, Cn (n ≥ 3), and reciprocal degeneracy of
eigenmodes. (iii) A new form of
circular dichroism is presented, which occurs due to the
interaction of nonorthogonal resonances, and impacts the ratio of
radiative scattering loss to dissipative absorption loss
experienced by reciprocal plane waves. Geometric asymmetry and
optical chirality are also reviewed to quantify the minimum
symmetries that must be broken to allow other circular dichroism
effects in chiral and achiral scattering objects. The sequence of
general theoretical conclusions (i)-(iii) serve to build the
understanding of optical scattering from nanoparticle systems
while removing existing ambiguities.

▼ Le sujet de cette thèse est l’analyse de la production de di-électrons dans des réactions induites par des pions avec le détecteur HADES a une énergie dans le centre de masse proche de 1.5 GeV, dans lesquelles des résonances baryoniques dans la deuxième région de résonances (N(1440), N(1520),..) peuvent être excitées. L’objectif est d’obtenir des informations sur les transitions électromagnétiques dans une région inexplorée cinématiquement, où l’on s’attend à ce que les mésons vecteurs jouent un rôle important. Ces mesures peuvent aussi être utilisées comme référence pour les études de production de paires e⁺e⁻ dans la matière hadronique visant à explorer les modifications de la fonction spectrale du ρ. Le document commence par une présentation des résultats déjà obtenus par la collaboration HADES pour la production de di- électrons. Suit une description de l’expérience HADES et de la ligne de faisceau de pions. Les différentes étapes de l’analyse sont ensuite présentées, en insistant sur l’identification des électrons. Une étude détaillée de l’ajustement de la réponse du détecteur RICH, qui est crucial pour la discrimination entre électrons et pions est réalisée. Puis, l’extraction du signal de production de di-électrons, ainsi que les problèmes de soustraction de la contribution de noyaux de carbone pour étudier les interactions pion-nucléon. Les outils existants pour l’interprétation des données sont ensuite introduits. En plus des modèles existants pour la réaction π⁻ρ →ne⁺e⁻, les résultats de l’analyse en ondes partielles des canaux 2πN peuvent être utilisés. La distribution de la masse invariante des paires e⁺e⁻ présente un excès par rapport à la production attendue pour des baryons ponctuels, ce qui confirme le rôle important de mésons _ hors-couche dans les facteurs de forme de transition électromagnétique dans ce domaine cinématique. Les résultats de l’analyse des distributions angulaires en utilisant le formalisme de la matrice densité sont aussi comparés`a un modèle théorique basé sur les contributions de plusieurs résonances. Cette comparaison montre que les distributions angulaires apportent des informations supplémentaires sur la structure des transitions baryoniques électromagnétiques. Cette analyse est utilisée pour motiver des expériences futures pour étudier les transitions électromagnétiques mettant enjeu des baryons non-étranges.
The subject of this thesis is the analysisof dielectron (e⁺e⁻) production channels produced in pion induced reactions with the High Acceptance Di-Electron Spectrometer (HADES) at a center of mass energy close to 1.5 GeV, where baryon resonances in the second resonance region (N(1440), N(1520),...) can be excited. The objective is to bring information on electromagnetic baryon transitions in an unexplored kinematic region, where vector mesons (ρ, w) are expected to play an important role. These measurements can also be used as a reference for studies of in-medium e⁺e⁻ production, investigating the modifications of the ρ meson spectral function. The document begins with…

▼ Cette thèse a pour but l’étude théorique de métamatériaux métalliques empilés. Ces structures sont actuellement proposées pour améliorer et élargir les fonctionnalités des métamatériaux métalliques. Nous portons un intérêt particulier aux propriétés de polarisation de ces structures métalliques empilées.En premier lieu, nous précisons le type de métamatériaux que nous étudions et nous présentons la méthode modale qui nous permet de décrire les propriétés électromagnétiques de la structure. A l’aide d’un Formalisme de Jones Etendu (FJE), développé récemment dans notre équipe, nous faisons ressortir les principales propriétés de polarisation linéaire de ces métamatériaux métallique.En alliant le FJE à l’algorithme de propagation de la matrice S, nous étudions un empilement de deux métamatériaux vus comme un montage polariseur-analyseur. Nous établissons ensuite une expression de la transmission de la structure: la loi de Malus étendue. Cela nous permet notamment de démontrer les résonances de type Fabry-Perot qui ont lieu entre les métamatériaux.Pour des structures plus conséquentes, nous montrons qu’il est possible de réaliser une rotation de la polarisation, à très faible perte et spectralement agile, grâce aux résonances de type Fabry-Perot.Fondamentalement, nous révélons une nouvelle façon d’exciter des résonances Fano qui sont induites par les propriétés de polarisation des métamatériaux. Ces résonances peuvent être utilisées pour des applications de capteur ou de filtrage. De plus, ces résonances Fano induites par la polarisation ouvrent de nouvelles possibilités d’applications pour les empilement de métamatériaux métalliques.
This PhD thesis deals with the theoretical study of stacked metallic metamaterials. Such structures are currently investigated to extend the functionalities offered by single metallic metamaterials. We especially focus on the specific polarization properties of the stacked metallic metamaterials.We first present the type of metamaterial that we consider, and we describe the modal method that is used to model its electromagnetic properties. We outline the linear polarization properties characterizing the metamaterial thanks to an Extended Jones Formalism (EJF) recently developed by our team.In combination with the EJF, we apply the S-matrix algorithm to the study of a stack of two metallic metamaterials in a polarizer-analyzer configuration. We derive an analytical expression for the transmission response of the stacked structure: the Extended Malus Law. Mainly, it highlights the Fabry-Perot-like resonances located between the metamaterials.Using larger stacked structures, we demonstrate that spectrally tunable and low loss polarization rotation can be achieved owing to these Fabry-Perot-like resonances.In essence, we reveal a new way of realizing Fano resonances which are induced by the specific polarization properties of the metamaterials. We show that such resonances can be engineered for sensing or filtering applications. Moreover, the polarization-induced Fano resonances expand the…

▼ This thesis presents a search for resonant production of top-antitop quark pairs in final states containing at least one electron or muon. A number of beyond the standard model (BSM) theories incorporate a specific role for the top quark, resulting in resonances that preferentially decay to t(bar over t) pairs. The data sample analysed corresponds to an integrated luminosity of 2.05 fb-1 recorded during 2011 using the ATLAS detector at the Large Hadron Collider. The proton-proton centre-of-mass energy was 7 TeV. The search is tailored towards heavy resonances at the TeV-scale which therefore decay to top quarks with high transverse momentum. Large hadronic jets are used to reconstruct the energy carried by the hadrons and the substructure of these jets is studied in order to identify hadronically decaying top quarks. The reconstruction can therefore proceed even if the decay products of the top quark are highly collimated. This study represents the first use of jet substructure techniques in a search for t(bar over t) resonances using hadron-hadron collision data. The invariant mass of the reconstructed t(bar over t) pair is used to test compatibility of the data with the standard model prediction. No evidence for t(bar over t) resonances is found. Upper limits are derived on the production cross-section times branching ratio for narrow and wide resonant states, at the 95 % credibility level. An upper limit of 0.61 (0.65) pb is set for a narrow (wide) resonance with a mass of 1 TeV. Two specific BSM models are excluded within certain mass ranges: the narrow leptophobic Z' boson with mass 600 - 1150 GeV and the wide Kaluza-Klein gluon with a mass below 1.5 TeV. These results represent a significant improvement on those of previous searches performed at the ATLAS experiment, which did not use jet substructure techniques. In addition, the possibility of using jets which decrease in size as their transverse momentum increases is investigated using simulated data. The yield of events due to resonant t(bar over t) production increases by approximately 20 % compared to when using jets of fixed size. Furthermore, the resolution of the invariant mass of the reconstructed t(bar over t) pair is found to improve by almost one fifth. It is recommended that a calibration scheme be developed for these variable-sized jets, so that their potential to improve the sensitivity to t(bar over t) resonances can be investigated further.

▼ We present a complex multicon figurational self-consistent field (CMCSCF)-
based approach to investigate electron{atom/molecule scattering
resonances. A modifi ed second quantization algebra adapted for biorthogonal spin orbitals has been applied
to develop a quadratically convergent CMCSCF scheme. A new step-length
control algorithm has been introduced in order to control the walk on the complex
energy hypersurface and converge to correct CMCSCF stationary point. We have
also developed a method (M1 method) based on the multiconfigurational spin tensor
electron propagator (MCSTEP) to calculate resonance energies directly.
These methods have been applied to investigate atomic and molecular scattering
resonances. The test cases for our application were 2^P Be- and 2II_g N-_2 shape
resonances. The position and the width of these
resonances have been calculated for
different complete active space choices. Convergence for CMCSCF calculations to
a tolerance of 1:0 x 10^-10 a.u. for the energy gradient is achieved typically within
ten iterations or less. The wide distribution of the values for the position and the
width of the resonance reported in the literature has been explained by showing that
there actually exists two distinct
resonances which are close in energy. The resonance
positions and widths from our calculation for the 2^IIg N-_2 shape resonance have been
found to be very close to the experimental results. In another study, the effect of the
orbitals with higher angular momentum has been investigated.

▼ The systematic exploration of excited meson and baryon states was the central topic of the COMPASS physics program in the years 2008 and 2009 at the CERN facility. A hadron beam of 190 GeV/c particle momentum was impinging on a 40 cm long liquid hydrogen target to create excited states of beam particles by diffractive processes. The presented work is about the study of the process K- p rightarrow K- pi+ pi- precoil where special emphasis is put on how kaons were distinguished from pions with the CEDAR detectors in the initial channel as well as with the RICH detector in the final states. At the end formed 270 000 events an invariant K pi pi mass distribution of overlapping resonances. In addition a detailed MC simulation study of 44 million decays in the range of 0.8 < m(K pi pi) [GeV/c2] < 3.0 was performed and analysed for acceptance corrections.All information was combined into a mass independent partial wave analysis to observe resonances of individual particles. The main contribution was found in the JP = 0+, 1+, 2- and 2+ spin-parity states.
Das Hauptziel des COMPASS-Physikprogramms in den Jahren 2008 und 2009 am CERN Forschungszentrum war die systematische Erforschung von Meson- und Baryonresonanzen. Es wurden hadronische Strahlteilchen mit 190 GeV/c Impuls auf ein 40 cm langes FlÜssig-wasserstoff-Target gelenkt, um über diffraktive Produktionsmechanismen angeregte Zustände der Strahlteilchen zu erzeugen. Die vorgestellte Arbeit beschäftigt sich mit dem Prozess K- p rightarrow K- pi+ pi- precoil. Es wird besonders darauf eingegangen, wie Kaonen von Pionen im Eingangskanal mit CEDAR Detektoren, als auch im Ausgangskanal mit dem RICH Detektor identifiziert wurden. Am Ende formten etwa 270 000 Ereignisse ein invariantes K pi pi Massespektrum aus verschiedenen sich überlappenden Resonanzen. Zusätzlich wurde eine detaillierte MC-Simulationsstudie durchgeführt, um im Ganzen 44 Millionen Zerfälle im Bereich von 0.8 < m (K pi pi) [GeV/c2] < 3.0 zu simulieren und auszuwerten. Alle Informationen wurden in einer massenunabhängigen Partialwellenanalyse zusammengeführt, um individuelle Teilchenresonanzen zu beobachten. Hauptbeiträge finden sich in den Spin-Paritätszuständen JP = 0+, 1+, 2- und 2+.

▼ The main objective of this thesis is to design and develop spectral signature
based chipless RFID tags Multiresonators are essential component of
spectral signature based chipless tags. To enhance the data coding capacity in
spectral signature based tags require large number of resonances in a limited
bandwidth. The frequency of the resonators have to be close to each other.
To achieve this condition, the quality factor of each resonance needs to be
high. The thesis discusses about various types of multiresonators, their practical
implementation and how they can be used in design. Encoding of data
into spectral domain is another challenge in chipless tag design. Here, the
technique used is the presence or absence encoding technique. The presence
of a resonance is used to encode Logic 1 and absence of a speci c resonance is
used to encode Logic 0. Di erent types of multiresonators such as open stub
multiresonators, coupled bunch hairpin resonators and shorted slot ground
ring resonator are proposed in this thesis.

▼ In the setting of obstacle scattering in Euclidean spaces, the poles of meromorphic continuation of the resolvent of the Laplacian on the exterior region are called the resonances or scattering poles. Each resonance corresponds to a resonant wave. The real part of a resonance corresponds to the frequency of the wave, while the imaginary part corresponds to the decay rate of the wave. Consequently understanding the distribution of the resonances is important in understanding the long time behavior of the solution to wave equations in the exterior domain. We study the distribution of resonances in the case of a strictly convex obstacle with smooth boundary. In particular, under general boundary conditions, we prove the existence of the cubic resonance free regions near the real axis. Moreover, if the obstacle is close to a sphere, in the sense that it satisfies certain pinched curvature conditions, we prove that the resonances close to the real axis are separated into cubic bands and in each band, the counting function of resonances satisfies a Weyl law. We also generalize these results to totally convex obstacles in more general asymptotic Euclidean metrics.

▼ A existência de um méson escalar-isoescalar leve, conhecido como ?, foi proposta pela primeira vez na década de 60. A partícula tinha então um papel importante na construção teórica das interações ?? mas, apesar dos esforços experimentais, ela não foi detectada nos anos que se seguiram. Essa situação foi radicalmente alterada em 2001, quando uma ressonância escalar foi descoberta nos canais ?+?- do decaimento D+ -> ?+?-?+ e recebeu o rótulo ?(500). Sua existência é bem estabelecida hoje em dia. Contudo, no tratamento dos dados dos vários grupos experimentais são empregadas expressões com pouca base teórica e, por isso, os valores de sua massa e largura ainda são mal conhecidos. Neste tipo de decaimento, a formação da ressonância pode se dar no vértice fraco. Em sua subseqüente propagação, ocorrem as chamadas interações de estado final, cuja descrição não é trivial. Normalmente, essas interações não são levadas em conta de maneira criteriosa na análise de dados experimentais. Neste trabalho introduzimos uma função _(s) que descreve a propagação e decaimento da ressonância em presença das interações de estado final. No regime elástico, a fase de _(s) é determinada pelo chamado teorema de Watson, segundo o qual ela deve ser a mesma do espalhamento. Conseguimos estabelecer, sem ambigüidades, como a informação do espalhamento deve ser usada de forma a determinar não somente a fase de _(s), mas também seu módulo. Nosso principal resultado é uma expressão para _(s) em termos da fase elástica e de uma outra fase relacionada a uma integral de loop bem controlada. Três casos particulares foram explorados numericamente: os modelos sigma linear e não linear e ainda um modelo fenomenológico que leva em conta o acoplamento de canais p´?on-p´?on e k´aon-k´aon. Em consonância com a teoria quântica de campos, nosso resultado incorpora a unitariedade, considera a ressonância como grau de liberdade explícito e representa, ainda, uma generalização do procedimento usual de unitarizacao pela matriz K. Por permitir uma ligação clara entre espalhamento e produção, a função _(s) pode ser útil na análise de dados experimentais e ajudar na determinação da posição do pólo do ? e de outras ressonâncias escalares.
The existence of a light scalar-isoscalar meson, known as ?, was suggested in the 60\'s. This particle played an important role in the theoretical construction of ?? interactions but, in spite of all experimental effort, it failed to be detected. This scenario changed radically in 2001, when a scalar-isoscalar resonance was discovered in the ?+?- channel of the D+ -> ?+?-?+ decay and was called ?(500). Nowadays, its existence is rather well established. However, in the analysis of experimental data, expressions loosely based on theory are employed and therefore its mass and width are still not well known. In this kind of decay, the production of the resonance may occur at the weak vertex. When it propagates, final state interactions take place. Usually these interactions are not properly taken into account in data analysis. In this…

▼ This thesis is an observational study of field line
resonances (FLRs), between 0.5-5 mHz, in the Earth’s magnetosphere,
and their correlation with Ultra Low Frequency (ULF) waves in the
solar wind. The mechanisms for these phenomena are not yet
completely understood and there is still great debate on the causes
of Field Line Resonances as well as the discrete and repetitive
nature reported by some studies. Many studies of FLRs have been
reported, in the past decades, and recent work has indicated that
discrete, continuous ULF waves in the solar wind may be responsible
for driving these FLRs giving rise to particular “magic
frequencies” (1.3, 1.9, 2.6 and 3.4 mHz). The premise of this study
was that “magic frequencies” existed and the intent was to test the
hypothesis that discrete ULF waves in the solar wind directly
driving them. We successfully created an efficient algorithm and
computer code to automatically detect ULF coherent waves over a
large area within the field of view (FoV) of any Super Dual Auroral
Radar Network (SuperDARN)’ station that could be later categorized
as a “Field Line Resonance”. A total of 121 FLRs were identified
during 2003 and their primary characteristics were obtained. For
the 121 FLRs found in this study, ‘magic frequencies’ were not
predominant in the general distribution. The frequency with more
occurrences was the first in the array, 0.6±0.1 mHz. The
observation of other frequencies showed a decreasing trend of
observation of occurrences for increasing frequency. Results also
showed deviations from the classification of FLRs by their
azimuthal wavenumber m (high-m vs. low-m) provided by previous
studies, in terms of their phase variation vs. magnetic latitude,
propagation (sundwards-antisunwards; eastwards-westwards) and
location. From the FLRs identified in this study we were not able
to classify them into the two distinct groups, based upon the FLR’s
azimuthal wavenumber m, but rather the classification involved many
other variables. Possible alternative classifications that better
adjust the observations in this study include the distinction of
FLRs detected during quiet or active geomagnetic times, FLRs
located either in or out of the plasmapause region, and
classification of FLRs as low-m, intermediate-m, and high-m.
Finally, we applied four different, complementary techniques to
evaluate the coherence between ULF waves in the solar wind,
detected by the Advanced Composition Explorer (ACE), and the FLRs
found in this study. We found that some specific magnetospheric
configurations (such as uniform plasma distribution in the flux
tubes or previous excitation of the magnetosphere at the driven
frequency) might play an important role in the mechanisms driving
the FLRs. Additionally, mechanisms other than ULF waves in the
solar wind might be involved in driving the FLRs, such as
pre-existing wave packets in the solar wind matching the natural
frequency of the flux tube with specific magnetospheric
configurations that allow the solar wind to drive the
FLRs.

▼ The development of charged particle accelerators is
today reaching far beyond the realm of fundamental particle physics
research. Many non-trivial social and political problems may find
part of their solution lies in accelerator physics. For example,
with fossil fuels becoming ever more controversial and expensive to
obtain, the use of Accelerator Driven Sub-critical Reactors (ADSR)
powered by rapid cycling, high current proton accelerators and
thorium fuel could become part of the energy solution. Through the
simplicity of the Bragg peak, cancer therapy could be enhanced
through the use of high repetition rate, variable energy proton
accelerators small enough to use in treatment centres. The growing
problem of long lived nuclear waste storage could become a moot
point through the use of high current, high power proton
accelerators coupled with neutron spallation.These rapidly growing
areas of study are fuelled by the development of the Fixed-Field
Alternating-Gradient (FFAG) accelerator, and more recently the
non-scaling FFAG. The FFAG has the ability to accelerate high
current, low quality bunches of particles in very short time scales
due to the fixed-field nature of its magnets. This rapid
acceleration can be of the order 500 nanoseconds to 1 microsecond
meaning a fast cycling rate of the machine is possible. This allows
the realistic development of the ADSR, proton therapy machine and
even the muon accelerator. The Electron Model with Many
Applications (EMMA) accelerator is the world's first linear
non-scaling FFAG and is an electron proof-of-principle accelerator
based at Daresbury Laboratory, UK. EMMA can accelerate over its
energy range of 10 - 20 MeV in approximately 5 - 10 machine
revolutions (~275 - 500 nanoseconds) using fixed-frequency novel
acceleration techniques. The accelerator contains fixed-field,
constant gradient quadrupole magnets which provide all the bending
and focussing to the particles. Due to the linear non-scaling
nature of EMMA, many transverse integer tune values are crossed
which typically cause resonant effects resulting in bunch
degradation and loss. It was proposed and demonstrated that rapid
crossing (in 5 - 10 turns) of integer tune values in EMMA did not
result in transverse amplitude growth and particle loss. If the
wider societal goals of the non-scaling FFAG are to be realised,
protons and other heavy ions must be accelerated. Current
technological limitations dictate that longer acceleration times of
the order 1000's of turns would be necessary in proton machines of
similar design to EMMA. Hence slower integer tune crossing was
studied using acceleration in a synchrotron bucket in EMMA. It was
found experimentally that below the nominal EMMA operating
acceleration rate of 2.0 MV per turn, instabilities begin to
manifest. This was indicated in the growth of closed orbit
distortion (COD) and through simulation it was found that betatron
amplitude growth coupled with COD resulted in eventual loss of
particles to the physical aperture when crossing integer tunes.

▼ In the first part of this study, we present results of fully self-consistent Hartree-Fock based random phase approximation calculations of the strength functions S(E) and centroid energies ECEN of isoscalar (T = 0) and isovector (T = 1) giant
resonances of multipolarities L = 0 - 3 in 40Ca, 48Ca, and 208Pb using a wide range of 34 commonly employed Skyrme type nucleon-nucleon effective interactions. We determined the sensitivities of ECEN and of the isotopic differences ECEN(48Ca) - ECEN(40Ca) to physical quantities, such as nuclear matter incompressibility coefficient, symmetry energy density and effective mass, associated with the Skyrme interactions and compare the results with the available experimental data.
In the second part of this study, we present a novel method, using the single particle Schrodinger equation, to determine the central potential directly from the single particle matter density and its first and second derivatives. As an example, we consider the experimental data for the charge density difference between the isotones 206Pb – 205Tl, deduced by analysis of elastic electron scattering measurements which corresponds to the shell model 3s1/2 proton orbit, and determine the corresponding single particle potential (mean-field). We also present results of least-square fits to parametrized single particle potentials. The 3s1/2 wave functions of the determined potentials reproduce fairly well the experimental data within the quoted errors. More accurate experimental data, with uncertainty smaller by a factor of two or more, may answer the question how well can the data be reproduced by a calculated 3s1/2 wave function.

▼ Elektrotehnika / Electrical
engineering
Sa najnovijim razvojem nanotehnologije došlo je do
ponovnog interesovanja za polje plazmonike. Nanoplazmonika povezuje
fotoniku sa nanonaukama tako što konfinira svetlost u nanometarske
zapremine, dok se manipulacija svetlošću na nanoskali bazira na
osobinama prostirućih i lokalizovanih površinskih plazmona. Važan
korak u eksploataciji plazmonskih nanostruktura je njihov dizajn i
karakterizacija. Najčešće korišćene tehnike za karakterizaciju se
baziraju na merenjima intenziteta. One daju informacije o
amplitudama reflektovanih ili transmitovanih talasa nakon njihove
interakcije sa uzorkom, ali ne daju nikakvu informaciju o njihovim
fazama. U ovom radu, formira se strategija za karakterizaciju
plazmonskih nanostruktura korišćenjem spektroskopske elipsometrije
(SE), koja sama po sebi meri odnos amplituda i razliku faza za dve
karakteristične polarizacije. SE je veoma brza, nedestruktivna,
neninvazivna, apsolutna i veoma precizna tehnika, ali zahteva
složeno modelovanje za interpretaciju eksperimentalnih rezultata. U
tu svrhu, korišćena su dva programska paketa COMSOL Multiphysics i
RET)COLO-2D. Odgovarajuće simulacije omogućuju izdvajanje
informacija koje nisu dostupne u samom eksperimentu. Proučavani su
i prostirući i lokalizovani površinski plazmoni, prvi pobuđeni u
fišnet nanostrukturama i drugi koji se javljaju u SRR (engl. Split
Ring Resonators). )zučavane fišnet strukture, bazirane su na
dvo-dimenzionom (2D) nizu pravougaonih rupa izbušenih u
zlato/silicijum dioksid/zlato tankim slojevima. Ove strukture
podržavaju jako konfinirane GPP (engl. Gap Plasmon Polariton) u
tankom dielektričnom sloju. Kada su rupe ozbušene u 2D periodičnu
mrežu veličine 500 x 600 nm2, moguće je direktno optičko
pobuđivanje GPP u bliskom infracrvenom delu spektra. Analizom
elipsometrijskih spektara, otkriveno je da su GPP efikasnije
pobuđeni i disperzija im manje odstupa od disperzije GPP u glatkoj
strukturi kada je upadna svetlost polarizovana duž kraćih ivica
rupa. Mogući razlog za ovakvo ponašanje je ekscitacija
lokalizovanih rezonanci rupa na učestanostima bliskim GPP. )pak,
simulacije u kojima su posmatrane manje rupe, pri čemu je zadržan
odnos širina/dužina kao kod originalnih fišnet struktura, pokazuju
da zavisnost od polarizacije postoji čak i kada se rezonanca rupe
me poklapa sa GPP rezonancama. Ovaj efekat je objašnjen pomoću
kvazi-statičke polarizabilnosti rupa. Optičko pobuđivanje
lokalizovanih plazmonskih rezonanci u 2D poređanim SRR posmatrano
je u srednjem infracrvenom delu spektra. Elipsometrijski spektri su
objašnjeni na osnovu izračunatih kompleksnih koeficijenata
refleksije za dve karakteristične polarizacije. Pokazano je da
izbor upadne ravni dosta utiče na formiranje SE spektara. Ako se
upadna ravan poklapa sa ravni simetrije, vrhovi u SE spektrima
odgovaraju parnim plazmonskim modovima, a kada je upadna ravan
ortogonalna na ravan simetrije, vrhovi potiču od pobuđivanja
neparnih modova. Kako su elipsometrijska merenja vršena pri kosim
upadnim uglovima, javlja se retardacija…

▼ Numerous extensions of the Standard Model (SM) predict the existence of new interactions with enhanced couplings to the top quark. The associated massive new particle described by these theories could be observed as a top-antitop quark resonance. In this work, I present a search for such
resonances using data recorded in 2016 with the CMS detector in proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC, corresponding to an integrated luminosity of 35.9 fb−1 . This search is performed in events containing one muon, at least two jets and missing transverse energy in the final state. The analysis is optimized for events where the top quarks have a large Lorentz-boost by using jet substructure variables and boosted decision trees to suppress sources of irreducible background. The results show that the SM background predictions are in agreement with the observed data. Thus, 95% Confidence Level upper limits on the production cross section times branching fraction of selected benchmark models are set.

▼ The peripheral hearing mechanism, which involves structures and mechanisms that exist between the pinna (part of the ear I can see) and the brainstem, consists of the outer, middle and inner ears. The purpose of this study was to examine the natural
resonances of our outer and middle ears and what role they play in determining an individual’s hearing thresholds. This was done through middle ear reflectance and Békésy audiometry.
Middle ear reflectance permits the opportunity to see how the outer and middle ears affect the acoustic signal across frequency (200-6000 Hz). Minimum audible pressure thresholds differ as a clinical tool in that they are a behavioral response that reflects the participant’s perception of the acoustic signal across frequency. Threshold refers to the softest sound that a person can hear at any given frequency. Minimum audible pressure thresholds can be determined at static octave intervals (250, 500, 100, 2000, 4000, and 6000 Hz) or through Békésy Audiometry, which involves a sweeping of frequencies from 125 Hz to 8000 Hz at much smaller frequency. This process results in a minimum audible pressure (MAP) curve made up of more discrete frequency intervals.
I hypothesize that the MAP curve will correlate strongly with the middle ear reflectance curve, suggesting that the natural
resonances of the outer and middle ears account for our varying sensitivity across frequency. To my knowledge, these correlations have not yet been examined.

▼ Much research has been done in the past couple of decades on the vibrations of rotating structures, such as helicopter and wind turbine blades. This is the consequence of ever increasing standards towards dynamic performance of these systems. Previous investigations have primarily dealt with constant rotational velocity, with a focus on the determination of the linear dynamic response. The rotational speed cannot always be considered constant due to fluctuating external loads or due to specific ramp-up regimes. This non-constant angular velocity brings about terms with time dependent coefficients in the equations of motion which can result in the existence of so-called parametric resonances. These resonance phenomena are quite unknown in this field of application. Nevertheless, they are of major concern to mechanical engineers because it can lead to structural damage due to large amplitude oscillations as a result of parametric resonances. In this thesis a fully geometrically nonlinear beam model is set up to study the fundamental behavior that causes parametric resonances in rotating blades. These equations are solved by means of two numerical approaches, the finite element method and the Galerkin method. The first one is used to obtain the linear modal properties. The Galerkin discretized equations are adopted to examine the linear and non-linear dynamics in time. The linear response is investigated to obtain the regions in which the unstable motions occurs due to parametric excitation. The non-linear response is obtained to show the stable post-critical behavior in these instability regions. Furthermore, it is shown that for specific values of the rotational speed and the parametric excitation frequency, instability occurs in each principal direction.

▼ The LHC and the ATLAS detector offer an unprecedented opportunity to test theories beyond the Standard Model of particle physics. Some of these theories predict heavy particles that would decay predominantly into a top and an antitop quark. This thesis presents a technique to experimentally measure the invariant mass (Mtt) of top-antitop pairs, event-by-event, allowing for a complete reconstruction of the Mtt spectrum. Two different models of heavy narrow
resonances were considered: a particle X with a negligible mass width, and a Z' particle. Under these models, no
resonances in the Mtt spectrum were found in 35.3 pb-1 of 7 TeV centre of mass proton-proton collision data. An upper limit on the production cross section times the branching ratio of the heavy particle decaying into a top-antitop (Sup) as a function of its mass (Mx or Mz) was established at a 95% confidence level. Including systematic errors, the observed (expected) Sup at 95% varies from 3.2 pb (27.9 +11.3 -19.9 pb) to 77.7 pb (9.8 +10.7 -5.6 pb) for Mx ranging from 760 GeV to 1000 GeV, and from 2.9 pb (55.9 +56.9 -47.0 pb) to 43.4 pb (7.8 +8.9 -4.7 pb) for Mz ranging from 700 GeV to 1000 GeV.
