Magnetic Quantum Walks of Neutral Atoms in Optical Lattices
(2018-09-17)
This thesis focuses on the simulation of the physics of a charged particle under an external magnetic field by using discrete-time quantum walks of a spin-1/2 particle in a two-dimensional lattice. By Floquet-engineering ...
Effective actions from string and M-theory: compactifications on G2-manifolds and dark matter in the KL moduli stabilization scenario
(2018-09-26)
In this thesis we study the emergence of four-dimensional effective actions from compactifications of higher-dimensional string/M-theory and explore some of their phenomenological implications.

Generation of dark matter in the early universe from BSM models
(2018-10-11)
For several decades the nature of Dark Matter (DM) has been elusive to physics. Explanations for its evidences have been stacked up and most of them require new particle physics. In this work, we explore the standard thermal ...
Production of Dark Matter in Cosmological Models with Low Reheating Temperature
(2018-10-23)
In standard cosmology it is assumed that dark matter (DM) is thermally produced during the radiation dominated era after an inflationary period. This has led to the prediction of weakly interactive massive particles (WIMPs) ...
An Investigation of Constraints on Dark Matter Models from Mono-jet Searches at LHC
(2018-10-31)
In this work we investigate the Weakly Interacting Massive Particle (WIMP) dark matter searches in colliders. We focus on the mono-jet searches and derive the upper bounds on the WIMP production cross-sections at the LHC. ...
Analysis of inclusive semileptonic B meson decays with τ lepton final states at the Belle experiment
(2018-06-15)
In this thesis, the measurement of the inclusive branching fraction of B→Xτν decays at the Belle experiment is presented. Previous measurements of the inclusive semileptonic b-hadron branching fraction BR(b→Xτν) in ...
Search for the H → bb Decay of the Standard Model Higgs Boson in Associated Production with Vector Bosons Using ATLAS Data at √s = 8 TeV
(2018-10-29)
In this thesis, a search for the H → bb decay of the Standard Model Higgs boson is presented. A dataset of 20.2 fb-1 recorded by the ATLAS detector at CERN is ......
