Search for dark matter produced in association with b-jets in proton-proton collisions at √s = 13 TeV with the CMS detector using full Run2 data
A search for dark matter particles in the events containing large missing transverse energy accompanied by b-quarks has been performed. The data collected by the Compact Muon Solenoid detector at the Large Hadron Collider ...
Phenomenological Explorations in Dark Matter
The previous decade has seen an explosive increase in explorations into the nature of dark matter (DM) encompassing astrophysical, particle and cosmological probes. We face today a large body of gravitational evidences ...
Chiral Phase Transition Temperature in 3-flavor QCD
The nature of the chiral phase transition in QCD with three massless
flavors of quarks remains unresolved despite being studied for nearly four decades. This
Ph.D. thesis is a study using Lattice QCD to determine the ...
Explorations in the Space of S-Matrices
S-matrix is one of the fundamental observables of the quantum theory of relativistic particles. The quantum dynamics of relativistic particles can be abstractly understood in terms of S-matrix bypassing a Lagrangian ...
Complexity and Entanglement: From quantum gravity to many-body systems
In recent years, complexity and entanglement have emerged as two fundamental computational measures and played a significant role in shaping our understanding of various phenomena, from the geometric nature of quantum ...
Aspects of Heavy Supersymmetry
The recent discovery of a Higgs boson with a mass around 125 GeV, taken together with experimental results from flavor factories, dark matter direct detection, and searches for SUSY particles in the LHC suggest that ...
A Study of the Low-Energy Spectrum and Phase Structure of a Yang-Mills Matrix Model
Yang-Mills theory is a non-Abelian gauge theory based on the gauge group SU(N), and lies at the heart
of the QCD, the theory underlying strong interactions. Due to the fundamental property of asymptotic
freedom, a study ...
Living on the Edge A Study of Boundary Modes In Two-dimensional Topological Systems
In the last few decades an enormous amount of research has been carried out on some novel
phases of matter called topological phases which are beyond the paradigm of Landau’s theory
of symmetry breaking. One of the ...
Efficient Quantum Algorithms for Linear Algebra Problems
Many simulation problems can be expressed as time evolution under specific interactions,
from some simple initial state to a final state whose properties are to be investigated. In this
context, the Hamiltonian evolution ...
Analytical Mellin-Barnes techniques with applications to two-loop SU(3) chiral perturbation theory and QED at higher loops
The present era is one of precision in particle physics. To account for the lacunae in the otherwise
successful Standard Model, observables are calculated to high precision in various theoretical models,
which are then ...
