Universal structure of the Drell-Yan process beyond threshold

Abstract

We review recent results in the investigation of threshold logarithms at next-to-leading power considering the case of the Drell-Yan cross section at NNLO. We first show how they can be reproduced with a method of region calculation. Then we move to an approach based on soft- collinear factorization, showing that the entire logarithmic structure can be reproduced by means of universal functions.
