A search for tWZ production at the ATLAS experiment
… with a W boson and a W boson (tWZ) is a rare Standard Model process that has never before been observed. The tWZ process will be a useful input into global Standard Model Effective Field Theory (SMEFT) fits due to its sensitivity to top-electroweak SMEFT coefficients in regions of high boson …

Flavourful beyond the Standard Model physics at current and future colliders
The Standard Model of particle physics successfully explains nearly all non-gravitational phenomena observed in nature. Yet, both theoretical considerations and experimental data suggest that the model is incomplete and must be extended. This thesis investigates "flavourful" beyond the Standard …

Measurement of Electroweak W Boson Production via Vector‐Boson Fusion in Proton–Proton Collisions at √s = 13 TeV with the CMS Detector
… a sensitive probe of the gauge structure of the Standard Model (SM) and of possible deviations from it. The first part of the work establishes the theoretical and statistical foundations of the measurement, introducing the mathematical structure of the SM and its Effective Field Theory (EFT) …

Parton Distributions in Beyond the Standard Model Theories
… experimental data under the assumption that the Standard Model (SM) of particle physics is complete; however, this can bias studies of beyond the Standard Model (BSM) physics if these SM-like PDFs are used in these analyses. It is important to quantify the extent to which this occurs, in order to …

Beyond Color: Lattice Gauge Theory for Strongly-Coupled Physics
… is the prototypical strongly interacting Quantum Field Theory (QFT). It is the interaction that yields the strong nuclear force that binds protons and neutrons together. The underlying mathematical picture of QCD is known exactly: it is an 𝑆𝑈(3) gauge theory coupled to six flavors of fermions (the …

Effective Field Theories for Physics Beyond the Standard Model
… of data gathered by the LHC has tested the Standard Model to an unprecedented level, with searches for physics beyond the Standard Model placing strong constraints on new physics. As these constraints become more stringent, it is increasingly likely that physics beyond the Standard Model …

Precision Frontiers in Proton Structure and their Interplay with the Search for New Physics
… to a focus on finding small deviations from the Standard Model (SM) via indirect methods. To this end, there is a need for our knowledge of SM backgrounds to be as precise as possible, through precise knowledge of partonic scattering amplitudes, proton structure and SM parameters. Alongside this, …
