#### The Higgs Boson as a Probe of Physics Beyond the Standard Model at the Large Hadron Collider

(2018-05-08)

The nature of interactions of fundamental particles is governed by symmetries. These interactions are well described by an elegant and simple SU(3)c x SU(2)L x U(1)Y symmetric gauge theory that we call the Standard Model ...

#### Topics in the Exploration of New Physics at the International Linear Collider with the inclusion of Beam Polarization

(2018-04-03)

The Standard Model of particle physics which attempts to describe all matter and all forces in the universe (except gravity),has been in agreement with most of the experiments till date. However theoretically and ...

#### Randall-Sundrum Model as a Theory of Flavour

(2018-04-11)

The discovery of the Higgs boson by the LHC provided the last piece of the puzzle neces- sary for the Standard Model (SM) to be a successful theory of electroweak scale physics. However there exist various phenomenological ...

#### Electronic Transport in Low-Dimensional Systems Quantum Dots, Quantum Wires And Topological Insulators

(2018-04-05)

This thesis presents the work done on electronic transport in various interacting and non-interacting systems in one and two dimensions. The systems under study are: an interacting quantum dot [1], a non-interacting quantum ...

#### Aspects of Higher Spin Theories Conformal Field Theories and Holography

(2018-05-30)

This dissertation consist of three parts. The first part of the thesis is devoted to the study of gravity and higher spin gauge theories in 2+1 dimensions. We construct cosmological so-lutions of higher spin gravity in 2+1 ...

#### Probing the Beyond Standard Model Physics in Top Quark and Dark Matter Sectors

(2018-05-22)

The Standard Model (SM) of particle physics provides the theoretical framework to describe the fundamental interactions among elementary constituents of matter. SM is supported by experiments to a high degree of accuracy, ...

#### An Efficient Quantum Algorithm and Circuit to Generate Eigenstates Of SU(2) and SU(3) Representations

(2018-04-18)

Many quantum computation algorithms, and processes like measurement based quantum computing, require the initial state of the quantum computer to be an eigenstate of a specific unitary operator. Here we study how quantum ...

#### Studies of Topological Phases of Matter : Presence of Boundary Modes and their Role in Electrical Transport

(2018-05-21)

Topological phases of matter represent a new phase which cannot be understood in terms of Landau’s theory of symmetry breaking and are characterized by non-local topological properties emerging from purely local (microscopic) ...

#### Conformal Bootstrap : Old and New

(2018-05-25)

Conformal Field Theories (CFT) are Quantum Field Theories characterized by enhanced (conformal) symmetries. They are interesting to Theoretical Physicists because they occur at critical points in phase transitions of various ...

#### Lessons for Conformal Field Theories from Bootstrap and Holography

(2018-02-06)

The work done in this thesis includes an exploration of both the conformal field theory techniques and holographic techniques of the Gauge/Gravity duality. From the field theory, we have analyzed the analytical aspects of ...
