Effective Field Theories for Physics Beyond the Standard Model
… Standard Model Effective Field Theory (SMEFT) using data from the Higgs, top, diboson and electroweak sectors, combining these four data sectors in a global fit for the first time. We will assess the interplay between these sectors, shedding light on the interplay between the Higgs and …

Global Standard Model analyses for new physics searches
… Circular Collider (FCC). EFTs, such as the SMEFT, enable model-agnostic new physics searches via global analyses of collider data. This thesis focuses on a possible pitfall in such studies: the risk of introducing a bias toward the SM by absorbing potential new physics signals within the …

Parton Distributions in Beyond the Standard Model Theories
… the Standard Model Effective Field Theory (SMEFT), and carry out a simultaneous determination of PDFs together with two parameters drawn from the SMEFT; we show that at the HL-LHC, there will be significant interplay between extraction of PDFs and SMEFT parameters. In Chapter 4, we perform a …

A search for tWZ production at the ATLAS experiment
… global Standard Model Effective Field Theory (SMEFT) fits due to its sensitivity to top-electroweak SMEFT coefficients in regions of high boson and boson transverse momenta. The process is also a relevant background in other top quark related measurements, such as the ttZ¯ cross section …

Precision Frontiers in Proton Structure and their Interplay with the Search for New Physics
… such as the SM Effective Field Theory (SMEFT), must be utilised effectively such that in the future it would be possible to confidently characterise a deviation that may be due to new physics. In this thesis we will present work that is a part of both of these complementary programmes. …

Beyond Color: Lattice Gauge Theory for Strongly-Coupled Physics
… is the Standard Model Effective Field Theory (SMEFT). The SMEFT process that is considered is neutrinoless double 𝛽 (0𝜈𝛽𝛽) decay, a hypothetical decay of two neutrons into two protons and two electrons. LGT is used to compute non-perturbative matrix elements for the unphysical 𝜋⁻→ 𝜋⁺𝑒⁻𝑒⁻ …
