The Study of The Standard Model Electroweak Precision Physics at Future Electron-Positron Colliders.
Doctoral Dissertation, University of Pittsburgh.
(Unpublished)
Abstract
Future electron-positron colliders, such as the CEPC, FCC-ee, and ILC, usher in a new precision frontier where the electroweak (EW) sector of the Standard Model (SM) of particle
physics can be scrutinized unprecedentedly, thereby unraveling the potential new physics beyond the Standard Model. For this purpose, one needs a deeper understanding of the SM, which is led by calculating radiative corrections to various well-defined observables, namely the electroweak precision observables (EWPOs) in the EW sector. However, to compare the
EWPOs predicted by the theory with what was measured in experiments, other ingredients contributing to the relevant cross-section, such as the initial and final-state QED and QCD
radiation effects, background contributions, and acceptance of the detector, also need to be taken into account. This thesis will first report the recently accomplished three-loop EW corrections to some important EWPOs. Secondly, a new software package GRIFFIN (Gaugeinvariant Resonance In Four-Fermion Interactions), aiming to study the gauge resonance, such as the Z-boson resonance, up to arbitrary higher order, in a manifestly gauge-invariant way will be introduced.
