Description

Scattering processes near threshold develop large logarithms, that need to be resummed. In my talk I will focus in particular on electroweak annihilation processes, 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.
