Bolometric Luminosities of Peculiar Type II-P Supernovae
Lusk, Jeremy (2018-08-02)In this work, I analyze the bolometric luminosities of several peculiar Type II-P supernovae which are thought to originate from the same class of blue supergiant progenitor stars as the famous SN 1987A. This analysis is ... -
The Electric Dipole Moment of the Tau Lepton as a Signature of CP Violation
Dewald, Andrew (2019-08-01)We calculate a one-loop level electric dipole moment (EDM) of the tau lepton that arises from scalar/pseudoscalar Higgs mixing in a type II two Higgs doublet model. Numerical results at m_0 = 125 GeV give an EDM of 3.66 ... -
Flavor Changing Neutral Currents in a General Two Higgs Doublet Model: Using an Extended Sector to Search for New Physics
McCoy, Brent; McCoy, Phillip (legal first name) (2017-08)In this dissertation I present studies of flavor-changing neutral Higgs interactions in a general Two Higgs Doublet Model. I focus on the analytic calculation of φ → tc and φ → τ μ where φ = h0 , H0 , A0 . In the case ... -
Higgs Phenomenology in the Standard Model and Beyond at LHC
Yang, Kesheng (2013)In this dissertation, the discovery potential of neutral Higgs bosons has been discussed respectively in the Standard Model (SM), minimal supersymmetric standard model (MSSM), and unified supersymmetric models. In the SM, ... -
Measurement of the top quark pair production cross section with a tau lepton in the final state at the center of mass energy of 8 TeV
Hasib, Ahmed (2016)This dissertation presents the measurement of the inclusive cross section of the top quark pair production in the final state of a tau lepton with associated jets. The dataset used in this measurement is collected by the ... -
Measurement of the Top Quark Pole Mass and QCD Radiation in Top Quark Pair Production using Electron-Muon Events with b-Tagged Jets in Proton-Proton Collisions at 7-8 TeV with the ATLAS Detector at the LHC
Bertsche, Carolyn (2015)As heavy as an atom of gold but much smaller than a proton, the top quark is the most massive fundamental particle known in the universe and an integral part of current particle physics research. The characteristics of the ... -
Measuring The Trilinear Higgs Couplings at LHC
Wickramarachchi, Priyangika (2015-12)The results from the Large Hadron Collider (LHC) indicate that the couplings of the Higgs boson to other particles are consistent with the Standard Model. The coupling of the Higgs boson to itself will be the final and ... -
MIXED AXION-NEUTRALINO DARK MATTER IN THE SUPERSYMMETRIC DFSZ MODEL
Serce, Hasan (2016)The lack of evidence for weak scale supersymmetry (SUSY) from LHC Run-I at √s = 8 TeV and Run-II with √s = 13 TeV results have caused a paradigm shift in expected phenomenology of SUSY models. The spectrum of sparticle ... -
MOLECULAR BEAM EPITAXY OF ANTIMONY QUANTUM WELLS FOR PROBING TOPOLOGICAL SURFACE STATES
Wickramasinghe, Kaushini (2017)A topoelectronic transition was predicted for an Sb quantum well (QW) as a function of QW thickness. Bulk Sb is a semimetal with a negative bandgap, with neither the conduction band minimum nor the valence band maximum at ... -
OBSERVATION OF SINGLE TOP QUARK WITH ASSOCIATED Z BOSON PRODUCTION AT THE LARGE HADRON COLLIDER USING THE ATLAS DETECTOR
Frizzell, Dylan (2019)The Standard Model of particle physics is the most well tested theory in modern physics. It provides the most fundamental description of the natural world using only a handful of particles and their interactions. At ... -
Observation of the triboson process pp → W±W∓γ and limits on anomalous quartic gauge couplings with the ATLAS detector
Wilbern, Daniel (2023-05-12)This thesis presents a search for evidence of $W^\pm W^\mp \gamma$ production from $p-p$ scattering with $\sqrt{s}$ = 13 TeV at the Large Hadron Collider using 140 fb$^-1$ of integrated luminosity. The case where the $W$ ... -
OPTIMIZATION OF THE SEARCH CRITERIA FOR DETECTING THE STANDARD MODEL HIGGS BOSON DECAYING TO WW^* BOSONS
Johnson, Coulton (2019)Abstract It is important to measure the properties of the Higgs boson that has been detected at the LHC to determine if it exactly matches the predictions of the Standard Model (SM) Higgs or if it deviates from those ... -
Probing Flavor Changing Higgs Interactions at LHC and Future Hadron Colliders
Jain, Rishabh (2020-08)In this dissertation, we discuss the prospect of discovering flavor changing neutral Higgs (FCNH) interactions with quarks and leptons at current and future hadron colliders. Particularly, we have looked for $t \to c h^0$ ... -
SEARCH FOR SUPERSYMMETRY IN FINAL STATES WITH TWO SAME SIGN LEPTONS OR THREE LEPTONS AND JETS WITH THE ATLAS DETECTOR AT THE LHC
Rifki, Othmane (2017-07-07)The Standard Model of particle physics is the culmination of decades of experimental and theoretical advancements to successfully describe the elementary particles and their interactions at low energies, up to 100 GeV. ... -
Search for vector-like quarks and dark matter in mono-top events in proton-proton collisions with the ATLAS detector
Wang, Qing (2019-05-10)This dissertation describes a search for events with one top-quark and large missing transverse momentum in the final state. Data collected during 2015 and 2016 by the ATLAS experiment from 13 TeV proton-proton collisions ... -

Spotting clusters, hunting for planets: a combined study of galaxy clusters in the X-ray and optical regime
Bhatiani, Saloni (2022-08)Observational studies of the distribution of galaxies in the Universe reveal inhomogeneity and structure on Mpc and larger scales. Galaxy clusters are the largest gravitationally bound structures containing a virialized ... -
Supersymmetry and the Prisoner of Naturalness
Savoy, Michael (2017-07-27)In this work, I will address three concerns of supersymmetry. The first is the notion of naturalness and how much fine-tuning exists in a model. Historical measures, ∆ HS and ∆ BG , have led to an over estimate of the ... -
Various Topics in Type Ia Supernovae
Jenks, Malia (2019-05-11)This work takes two approaches to increasing our understanding of type Ia supernovae. The first part uses observations to study their spectral evolution and diversity. The second part uses modeling to investigate a potential ... -
WEAK SCALE SUPERSYMMETRY FROM THE MULTIVERSE
Sengupta, Dibyashree (2020)The CERN Large Hadron Collider (LHC) has not found any experimental evidence yet for Supersymmetric (SUSY) particles. This has pushed the limits on the masses of SUSY particles in the multi-TeV region high enough to question ...
