摘要

We renormalize the soft function entering the factorization and resummation of the qg parton-scattering channel of the Drell-Yan process near the kinematic threshold s ̂ \( \hat{s} \) → Q2 at next-to-leading power in the expansion around z ≡ Q2/ s ̂ \( \hat{s} \) = 1, and solve its renormalization-group equation.
