Searches for Vector-Like Quarks decaying to W bosons and module placement quality assurance for the ATLAS ITk upgrade. / Stewart, Joshua Ryan
This dissertation explores the realm of particle physics through two distinct yet interconnected lenses: the search for Vector-Like Quarks (VLQs), and the quality assurance in module placement for the ATLAS Inner Tracker (ITk) upgrade in preparation for the High Luminosity Large Hadron Collider (HL- [...]

A search for third-generation leptoquarks in the non-resonant production with the ATLAS experiment and development of the Level-0 muon trigger for the High Luminosity LHC / Morodei, Federico
Recent observations performed by several high-energy physics experiments have shown anomalies in b-hadron decays, which could be explained by assuming the existence of a particle, the leptoquark, coupled both to leptons and quarks [...]

Extending the Reach of Searches for Staus, Charginos and Neutralinos with the ATLAS Experiment at the Large Hadron Collider / Jones, Dominic
This thesis describes new approaches to extend the sensitivity reach of searches for three types of supersymmetric particles; staus, charginos and neutralinos, using the $139~\text{fb}^{-1}$ of data collected with the ATLAS experiment at the Large Hadron Collider between 2015 and 2018 [...]

Measurements of the Differential Charged-Current Drell-Yan Cross-Section and Muon Charge Asymmetry at High Transverse Masses with the ATLAS Detector / Mandalia, Jesal
This thesis presents the measurements of the $W \rightarrow \mu \nu$ charged-current Drell-Yan process, utilising the experimental data recorded by the ATLAS experiment during the $\mathrm{Run-2}$ period of $pp$ collisions at the LHC at $13~\mathrm{TeV}$, corresponding to a total integrated luminosi [...]
