Phenomenological Studies Of Dark Matter
(Physics, 2014-07-14)It is common knowledge that eighty percent of the matter in our Universe consists of a mysterious substance called ``dark matter'' (DM) which has only been detected through its gravitational interactions. The ``Standard ... -

PLASMA-BASED SYNTHESIS OF NANOSTRUCTURED MATERIALS AND THEIR CHARACTERIZATION
(2017-05-02)The aim of this thesis is to explore the novel cost-effective synthesis technique to develop nanostructured materials and investigate their structural and magnetic properties. Nanomaterials were synthesized by a plasma ... -
Precision Higgs Coupling Measurements In H→ww*→lνlν Final State With The Atlas Detector At The Lhc
The Standard Model (SM) is a gauge theory that describes the fundamental particles of matter and the forces between these particles. It has been tested to a very high precision in the past several decades, except for ... -
Probing The 5f Electrons: A Relativistic DFT Study Of Americium Surfaces
(Physics, 2008-09-17)Surface chemistry and physics have been and continues to be very active fields of research because of the obvious scientific and technological implications and consequent importance of such research. One of the many ... -
Propagation And Generation Of Waves In Solar Atmosphere
(Physics, 2010-03-03)The fact that the temperature increases with height in the solar atmosphere has been known for many years. To maintain this temperature increase, sources of heating must be present in the atmosphere. One of the most ... -
PROSPECTS FOR OBSERVING DYNAMICALLY FORMED BINARY BLACK HOLES IN THE LOCAL UNIVERSE WITH GRAVITATIONAL WAVES
(2018-06-07)The dynamical evolution of globular clusters is expected to produce stellar-mass binary black holes with higher total mass than found in the field population of binary black holes. Such systems are identified as gravitational ... -
Quantum Modeling Of Dark Matter In Galactic Halos
(Physics, 2013-03-20)Eighty years after its initial discovery, the nature of dark matter remains a mystery. Contrary to observational evidence, simulations of dark matter halos predict cuspy density profiles and an abundant population of dwarf ... -
The Role Of The Y-component Of The Interplanetary Magnetic Field In Transpolar Saturation And Ring Current Response As Found In Data And Simulation
(Physics, 2010-07-19)Energy is transferred into the magnetosphere of Earth through merging of magnetic fields (Dungey cycle and lobe cell convection) and through momentum transfer across the magnetopause (viscous interactions). These processes ... -
SCATTER CORRECTION AND 4D RECONSTRUCTION OF CONE BEAM COMPUTED TOMOGRAPHY (CBCT) WITH A MOVING BLOCKER
(2018-08-08)Come-beam computed tomography (CBCT) is being widely used as an image guidance tool in radiation therapy nowadays. The quality of CBCT image is important to localize and delineate the tumor and to define relevant volumes ... -
Search For A Supersymmetric Partner To The Top Quark Using A Multivariate Analysis Technique.
Supersymmetry (SUSY) is an extension to the Standard Model (SM) which introduces supersymmetric partners of the known fermions and bosons. Top squark (stop) searches are a natural extension of inclusive SUSY searches at ... -
Search For Standard Model Higgs In Two Photon Final State At Atlas
(Physics, 2010-11-01)The Standard Model of particle physics describes very precisely the nuclear strong and weak forces and the eletromagnetic interaction, by the exchange of vector bosons. It also describes all matter as composed of quarks ... -
Search For Supersymmetry In Dijet And Multijet Channels And Soft QCD Measurements Using The ATLAS Detector At The Large Hadron Collider
(Physics, 2011-03-03)The ATLAS experiment at the CERN Large Hadron Collider (LHC) has collected a substantial amount of data to understand the Standard Model of particle physics at higher than previous center of mass energy available and to ... -

Searches for Supersymmetric Particles with the ATLAS Detector using Boosted Decay Tree Topologies
(2016-08-05)The existence of a scalar Higgs particle poses a challenge to the Standard Model through an unnatural hierarchy problem with quadratic divergence. A supersymmetric framework, proposing heavy partners to every Standard Model ... -
Searches For The Exclusive Higgs and the Charged Higgs Bosons with the ATLAS Detector at the LHC
(2016-12-06)In this thesis, searches for the exclusive Standard Model (SM) and charged hMSSM Higgs bosons are performed. While observations of the SM Higgs boson in 2012 by ATLAS and CMS collaborations were ground-breaking, several ... -
Searching for a Pair-Produced Supersymmetric Top Partner Using Recursive Jigsaw Variables and Boosted Decision Trees with 139 fb⁻¹ of Data From the ATLAS Detector
