A High Precision Measurement of the Proton Charge Radius at JLab
(2020)The elastic electron-proton ($e-p$) scattering and the spectroscopy of hydrogen atoms are the two traditional methods to determine the proton charge radius ($r_{p}$). In 2010, a new method using the muonic hydrogen ... -
A Measurement of the Production Cross Section of a Single Top Quark in Association with a $W$-boson at $\sqrt{s} = 13$ TeV with the ATLAS Detector at the Large Hadron Collider
(2020)A measurement of the Standard Model cross section for the production of a single top quark in association with a $W$-boson from proton-proton collisions is presented. Collision data at a center-of-mass energy of 13 TeV totaling ... -
A Search for Supersymmetry in Multi-b Jet Events with the ATLAS Detector
(2019)A search for supersymmetry in pair-produced gluinos decaying via top squarks to the lightest neutralino is presented. Events with multiple hadronic jets, of which at least three must be identified as originating from b-quarks, ... -
Alternative Tests of Quarkonium Production Theory Using Jets
(2017)In this thesis I discuss an alternative approach for investigating quarkonium production in hadron colliders. I present a complete framework for developing observables for studies of charmonium states produced within a jet. ... -
An Improved W Boson Mass Measurement using the Collider Detector at Fermilab
(2012)The mass of the $W$ boson is one of the most important parameters in the Standard Model. A precise measurement of the $W$ boson mass, together with a precise measurement of the top quark ... -
An Inclusive Analysis of Top Quark Pair, W Boson Pair, and Drell-Yan Tau Lepton Pair Production in the Dilepton Final State from Proton-Proton Collisions at Center-of-Mass Energy 7 TeV with the ATLAS Detector
(2013)A simultaneous measurement of three Standard Model cross-sections using 4.7 inverse femtobarns of proton-proton collision data at a center-of-mass energy of 7 TeV is presented. Collision data were collected using the ATLAS ... -
Application of Effective Field Theory in Nuclear Physics
(2019)The production of heavy quarkonium in heavy ion collisions has been used as an important probe of the quark-gluon plasma (QGP). Due to the plasma screening effect, the color attraction between the heavy quark antiquark pair ... -
Applications of Gauge/Gravity Duality in Heavy Ion Collisions
(2014)In order to analyze the strongly interacting quark gluon plasma in heavy ion collisions, we study different probes by applying the gauge/gravity duality to facilitate our qualitative understandings on such a non-perturbative ... -
Constraining Non-Standard Neutrino Interactions and Estimating Future Neutrino-Magnetic-Moment Sensitivity With COHERENT
(2020)Neutrinos represent a rich field of physics that contains many theoretical problems that are yet to be solved and experimental results hinting at physics beyond the standard model of particle physics (BSM). An experiment ... -
Evidence of Higgs Boson Production through Vector Boson Fusion
(2015)The discovery of the Higgs boson in 2012 provided confirmation of theproposed mechanism for preserving the electroweak $SU(2) \times U(1)$gauge symmetry of the Standard Model of particle physics. It alsoheralded in a new ... -
Exclusive Photodisintegration of 3He
(2019)Kinematically complete measurements of three-body photodisintegration of $^3$He were performed at the High Intensity $\gamma$-ray Source (HI$\gamma$S) with nearly monoenergetic 15 MeV photons. The experiment relied on two-nucleon ... -
Experiments of Search for Neutron Electric Dipole Moment and Spin-Dependent Short-Range Force
(2012)It is of great importance to identify new sources of discrete symmetry violations because it can explain the baryon number asymmetry of our universe and also test the validity of various models beyond the standard model. ... -
Exploring Quantum Field Theories with Qubit Lattice Models
(2020)The framework of quantum field theory (QFT) underlies our modern understanding of both particle physics and condensed matter physics. Despite its importance, precise quantitative calculations in strongly-coupled theories ... -
Fermion Bag Approach for Hamiltonian Lattice Field Theories
(2018)Understanding the critical behavior near quantum critical points for strongly correlated quantum many-body systems remains intractable for the vast majority of scenarios. Challenges involve determining if a quantum phase ... -
Initial Conditions of Bulk Matter in Ultrarelativistic Nuclear Collisions
(2019)Dynamical models based on relativistic fluid dynamics provide a powerful tool to extract the properties of the strongly-coupled quark-gluon plasma (QGP) produced in the first ${\sim}10^{-23}$ seconds of an ultrarelativistic ... -
Measurement of Muon Neutrino Disappearance with the T2K Experiment
(2014)We describe the measurement of muon neutrino disappearance due toneutrino oscillation using the Tokai-2-Kamiokande (T2K) experiment's Run 1-4 (6.57×10<super>20</super> POT)data set. We analyze the data using ... -
Search for Heavy Boson Resonances in Final States with a W or Z Boson and a Photon Using 139 \fb of Proton-Proton Collision Data at sqrt(s) = 13 TeV Collected with the ATLAS
(2020)This thesis presents a search for boson resonances that decay into an energetic photon and the Standard Model's W or Z boson: $X \to W\gamma$ and $X \to Z\gamma$. The dataset used for the measurement was collected at the ... -
Speculative Physics: the Ontology of Theory and Experiment in High Energy Particle Physics and Science Fiction
(2014)The dissertation brings together approaches across the fields of physics, critical theory, literary studies, philosophy of physics, sociology of science, and history of science to synthesize a hybrid approach for instigating ...
