Description

In this talk I present a new endpoint factorization theorem that generalizes the classic soft threshold factorization for Drell-Yan-like processes. It fully captures both soft and collinear dynamics, including nondiagonal partonic channels that are neglected in the standard soft limit. This allows us to construct a fixed-order approximant for the cross section that covers all singular limits in the partonic momentum fractions. Our factorization also enables the resummation of all large-$x$ logarithms appearing in the Drell-Yan rapidity spectrum toward large rapidities.
