Next-to-soft radiative corrections in QCD and quantum gravity

Melville, Stacey Elizabeth (2016) Next-to-soft radiative corrections in QCD and quantum gravity. PhD thesis, University of Glasgow.

Abstract

The origin of divergent logarithmic contributions to gauge theory cross sections arising from soft and collinear radiation is explored and a general prescription for tackling next-to-soft logarithms is presented. The NNLO Abelian-like contributions to the Drell-Yan K-factor are reproduced using this generalised prescription. The soft limit of gravity is explored where the interplay between the eikonal phase and Reggeization of the graviton is explained using Wilson line techniques. The Wilson line technique is then implemented to treat the set of next-to-soft contributions arising from dressing external partons with a next-to-soft Wilson line.
