 Threshold factorization and resummation of the Drell-Yan process at next-to-leading-power
Abstract: Soft Collinear Effective Theory (SCET) formalism has been successfully applied to many important observables in collider physics, improving the accuracy of fixed-order predictions via the leading power resummation of large logarithmic contributions which appear in certain regions of phase space. Recently, a renewed interest in subleading power corrections has arisen in the theoretical community. In this talk, I will discuss the framework for the threshold resummation of the Drell-Yan process at next-to-leading power using SCET. I will explain how to derive the general factorisation formula and discuss the new objects that emerge beyond leading power: collinear jet functions and generalized soft functions. The leading logarithmic solution of the RG equations will be presented, and I will perform a comparison with known fixed order results.
