Renormalization of the next-to-leading-power soft function for the Drell-Yan off-diagonal channel
Abstract 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 ̂ $$ \hat{s} $$ → Q 2 at next-to-leading power in the expansion around z ≡ Q 2/ s ̂ $$ \hat{s} $$ = 1, and solve its renorm...

| Summary: | Abstract 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 ̂ $$ \hat{s} $$ → Q 2 at next-to-leading power in the expansion around z ≡ Q 2/ s ̂ $$ \hat{s} $$ = 1, and solve its renormalization-group equation. |
