Jet physics at ATLAS
… to generate next-to-leading order predictions of jet cross-sections, independent of parton distribution functions, was investigated. Such methods were found to provide an accurate approximation to a standard Monte-Carlo simulation (within 1%) and enable collider data to be readily included in …

QCD jet evolution at high and low scales
… of aspects that concern the simulation of QCD jet physics by Monte Carlo event generators. Phenomenological work is presented in validating the CKKW approach for merging tree-level matrix elements and parton showers. In the second part the main project is documented comprising the definition, …

The reconstruction of high-pt photons with the electromagnetic calorimeter of the ALICE experiment at the LHC
… years, the frontier of relativistic heavy ion physics will move to the Large Hadron Collider (LHC), which will explore matter with energy densities greater than 10 times that at the Relativistic Heavy Ion Collider (RHIC), providing an opportunity to test predictions of Quantum Chromodynamics …

High cadence optical polarimetry for time domain astronomy on the Liverpool Telescope
… form a fast moving field of research within astrophysics which relies on multi-wavelength observations of these transient events to probe the early- time (< 15 minutes) parameter space of these events. In the optical regime, follow-up observations to the prompt emission are ideally suited to the …

Modern Methods in Machine Learning as Applied to the Study of a Complex Supersonic Jet Flow
… stealth performance. The associated turbulent jet physics and the aeroacoustic phenomena have been studied thoroughly over the past 80 years; however, the complex non-linear interactions between multiple merging canonical flows are not well understood. In this study, we seek to gain a better …

A New Formalism for Soft Collinear Effective Theory with Applications
In this thesis a new formalism for Soft Collinear Effective Theory (SCET) is developed and a new calculation relevant to high-precision studies of Quantum Chromodynamics (QCD) involving the summation of Sudakov double logarithms is presented. The new formalism of SCET possesses certain desirable …
