Resummation of next-to-leading power logarithms for scattering processes near threshold

Abstract

Scattering processes near threshold develop large logarithms, that need to be resummed. In my talk I will focus in particular on electroweak annihilation processes, such as Drell-Yan and Higgs production in gluon fusion, and discuss the underlying factorisation theorems which allow the resummation of such logarithms at next-to-leading power, comparing diagrammatic and effective field theory methods.
