▼ The top quark is the heaviest of the six observed
quarks in the Standard Model (SM). Its mass is more than an order
of magnitude greater than any other SM fermion, and hence a precise
measurement of this mass provides constraints on the Higgs boson
and many other hypothetical particles. In this analysis, we measure
the mass of the top quark using the 36 pb-1 of data collected by
the CMS experiment from the collisions of the LHC at √s = 7 TeV
center-of-mass energy during the year 2010.
At the LHC, top-antitop quark pairs are expected to be
produced predominantly through gluon fusion and decay almost
exclusively to two W bosons and a bottom-antibottom quark pair. We
consider a W boson decay leptonic if it results in a muon or an
electron and label the decay channel based on the number of
leptonic W decays. Here, we report on the measurement of the mass
of the top quark in the dilepton channel.
The dilepton final state consists of two jets originating
from the bottom quarks, two charged leptons and two neutrinos. The
latter are not visible to our detector, which results in six
unknown parameters. Five of these can be solved for using
constraints arising from transverse momentum conservation, the mass
of the W boson and the equality of masses of the top and antitop
quarks. To deal with the under-constrained system, we use the
Analytical Matrix Weighting Technique. This method iterates over
many values of the top quark mass and analytically solves the
system using the top quark mass as the missing constraint. Each
value of the mass is given a weight based on the kinematics of top
quark production and decay. The mass estimator for each event is
the value with the highest weight and the mass of the top quark is
extracted from these estimators by performing a maximum likelihood
fit to simulated templates constructed for various masses. The
measured value of the top quark mass from this analysis is mt =
175.8 ± 4.9 (stat) ± 4.5 (syst) GeV/c2.

▼ In this thesis we first study various aspects of
stationary distributions of certain deterministic and stochastic
dynamical systems. We look at the 30 year old proposal to use
complex Langevin equations to sample complex path integral weights
of quantum field theories. We solve for possible stationary
distributions of complex Langevin equations and relate these to the
solution space of Schwinger-Dyson equations. We introduce an
effective potential for the whole complex Langevin evolution, which
allows us to identify the particular stationary distribution
sampled. Next we look at deterministic dynamical systems and ask a
very general question: Can one engineer dynamical systems with a
given stationary distribution? We explicitly engineer such systems
and using this knowledge we introduce novel Monte Carlo based
methods to calculate various quantities associated with these
dynamical systems. Through Monte Carlo simulations and series
resummations, we study the analytic structure of the associated
autocorrelation functions, which gives the exponential decay
constant of the power spectrum. Finally we study a first order
phase transition in large Nc, N=2 SYM theory using the methods of
AdS/CFT correspondence. We discuss AdS/CFT description of the
latent heat in the phase transition. We further investigate an
out-of-equilibrium evolution of the theory at high temperatures.
Through AdS/CFT correspondence, this problem is mapped to an
evolution of a D7-brane in a time-dependent gravitational
background.

▼ We discuss a discontinuous Galerkin (dG) method and
its application to common partial differential equations which
arise in the context of general relativity. First we consider
extreme mass ratio binary (EMRB) systems. When modeling EMRBs as
perturbations of a Schwarzschild black hole, the metric
perturbations are described by the distributionally forced
Regge-Wheeler-Zerilli (RWZ) equation. Despite the presence of jump
discontinuities in the solution, our dG method achieves pointwise
spectral accuracy. Particular attention is given to the common
choice of trivialinitial data, and we show such unphysical
specification may lead to spurious solutionswhich contaminate the
physical solution indefinitely. Unintended consequences of
thepersistent junk solution are considered as well as a simple
prescription for removing it. Using our code we compute metric
perturbations, gravitational waveforms, and self-force measurements
from both circular and eccentric orbits.Next, we present a dG
method for evolving the spherically reduced Generalized
Baumgarte-Shapiro-Shibata-Nakamura (GBSSN) system expressed in
terms of second-order spatial operators. Our multi-domain method
achieves global spectralaccuracy and long-time stability on short
computational domains. We discuss in detail both our scheme for the
GBSSN system and its implementation. A theoretical and
computational verification of the proposed scheme is given.We
conclude with a preliminary look at reduced basis (RB) methods for
parameterized binary systems. Our algorithm aims to construct a
compact RB space from which a particular solution can be quickly
and accurately recovered. We apply the algorithm to compress the
space of analytic chirp gravitational waveforms. Next, the RWZ
equation is revisited, and we consider extensions of the algorithm
to a dG solver along with numerical evidence that a RB space exists
for EMRB waveforms.

▼ The Standard Model (SM) has stood as one of the
cornerstones of modern physics for the past 40 years; yet it is
likely to remain only as an effective field theory. In particular,
new beyond the SM theories are required to explain both the
baryon-antibaryon asymmetry observed in the Universe and the
unnatural lightness of the tentatively observed Higgs boson. Such
theories often predict heavy partners to the six observed quarks,
which naturally explain these phenomena.
In this thesis, we present two searches for a heavy top-like
quark at the LHC using data collected by the CMS detector. In 2011,
we searched for a sequential fourth generation quark t' using 5fb-1
of data at a 7TeV centre of mass energy. In 2012, we searched for a
vector-like T that partners the SM top quark using 19.6fb-1 of data
at 8TeV.
In both analyses, we used a semileptonic event topology,
consisting of events with exactly one lepton. No excess over SM
predictions are observed and the heavy top-like quark is ruled out
below the mass of 700GeV/c2 across the entire phase space. This is
the first analysis of its kind and we set the most stringent limit
on this entire class of beyond the SM theories to
date.

▼ We review a field theory approach to Higher Spin
Gravity in 4 dimensional Anti de Sitter (AdS) space within the
framework of the AdS/CFT correspondence. Based on large N
collective field theory of vector type models, we develop a
bi-local dipole picture of Higher Spin theory. We also describe a
geometric (Kahler space) framework for the bi-local theory which
applies to Sp(2N) fermions and potentially to the de Sitter (dS)
correspondence. We discuss in this framework the structure and size
of the bi-local Hilbert space and the implementation of (finite N)
exclusion principle. For the correspondence based on free CFTs we
first discuss the transformation for O(N) collective field and the
Higher spin filed, and then the nature of bulk 1/N interactions
through an S-matrix which by the Coleman-Mandula theorem is argued
to be equal to 1.

▼ In this thesis we address the question of pattern
selection in spatially extendedsystems in the presence of
stochastic noise. As a model equation, we study the1D stabilized
Kuramoto Sivashinsky equation with additive uncorrelated
stochasticnoise. This equation is one of the simplest nonlinear
equations that has a variety ofsecondary and even tertiary
instabilities. We focus our attention on static stationarystates
that are stable against the Eckhaus secondary instability. In the
presence ofnoise the Eckhaus stable band of the deterministic
equation collapses to a narrowregion near the center of the band.
This is consistent with the behavior of the phasediffusion
constants of these states. Some connections to the phenomenon of
stateselection in driven out of equilibrium systems are
made.

Symmetry Breaking: A New Paradigm for Non-Perturbative QFT

(more)
▼ After ~50 years, there seems to be a convergence in
the languages used to describe Quantum Field Theory and String
Theory, such that it seems possible to relate objects from these
two perspectives. Therefore, a deeper investigation of the
properties and features of QFT is a reasonable thing to do:
nonperturbative effects, dualities, emergent properties,
noncommutative structures, etc. This particular line of research
uses Symmetry Breaking in order to probe a few of the different
topics mentioned above, i.e., Symmetry Breaking is used as an
"underlying principle", bringing different features of QFT to the
foreground. However, the understanding of Symmetry Breaking that is
used here is quite different from what is done in the mainstream:
Symmetry Breaking is understood as the solution set of a given QFT,
its vacuum manifold, or, more modernly, its Moduli Space. Distinct
solutions correspond to different sectors, phases, of the theory,
which are nothing but distinct foliations of the vacuum manifold,
or points in the Moduli Space (for all possible values of the
parameters of the theory). Under this framework, three different
problems will be attacked: "Mollifying QFT", "Topological
Transitions and Geometric Langlands Duality" and "Three-dimensional
Gravity and its Phase Transitions". The first makes use of the
Moduli Space of the theory in order to construct an appropriate
mollification of it, rendering it viable to simulate a QFT in
Lorentzian spaces, tackling the "sign problem" heads-on. The
connections with Lee-Yang zeros and Stokes Phenomena will be made
clear. The second will show that each different phase has its own
topology which can be used as Superselection Rule; moreover, the
Euler Characteristic of each phase gives it quantization condition.
The mechanism via which several dualities work will also be
elucidated. The last one will generalize a 0dimensional QFT, via
dimensional construction through its D-Module, and conjecture
several connections between the Lie-algebra-valued extension of the
Airy function and the recent Partition Function found for
3dimensional gravity with a negative cosmological constant. These
three problems, put together, should exhibit a solid and robust
framework for treating QFT under this new paradigm.

Finite-Temperature Quantum Electrodynamics: General Theory

(more)
▼ Finite-temperature quantum field theory, with a focus
on Quantum Electrodynamics (QED), and its application to the
scattering of an ultra-relativistic particle in a hot plasma, are
presented in terms of Schwingerian functional methods and a new
variant of Fradkin's representation. The phenomena of a fast moving
fermion entering into a hot QED plasma is described by the
finite-temperature fermion propagator in a high temperature medium
under the assumption that the energy scale of the incident particle
is much larger than the temperature scale of the medium. The
incident particle loses energy and momentum through exchange of
both virtual and thermal photons with the thermal bath, which, in
turn, creates a disturbance in the medium until it becomes a part
of the thermal bath. Three energy-depletion mechanisms are
investigated through the damping of the finite-temperature fermion
propagator in the functional approach: thermal-photon enhanced and
ordinary Bremsstrahlung, and pair production. The damping of the
incident particle is estimated in a non-perturbative,
systematically functional way under the Bloch-Nordsieck
approximation, which not only extracts contributions from soft
photons, but also includes effects of momentum decreasing during
the process, and the results are physically correct, gauge
invariant, and free of any IR and/or UV divergence which has
plagued previous perturbative attempts. In contrast to
time-dependent, linear or logarithmic exponential type decays of
previous perturbative calculations, the results show the incident
particle experiencing much faster damping in a Gaussian fashion.
The disturbance inside the QED plasma is also modeled; a symmetric
"fireball" first rises as energy depletion of the incident
particle, and subsequently damps away in the same, Gaussian fashion
as the incident particle. Results of perturbative calculations and
Hot Thermal Loop approximations are compared and critiqued. Thermal
mass-shift, impact of gauge-dependence, and other aspects of
finite-temperature QED are briefly discussed, and a possible
extension to QCD is also presented.
