Threshold factorization of the Drell-Yan quark-gluon channel and two-loop soft function at next-to-leading power
Abstract We present a factorization theorem of the partonic Drell-Yan off-diagonal processes g q ¯ qg → γ ∗ + X $$ g\overline{q}(qg)\to {\gamma}^{\ast }+X $$ in the kinematic threshold regime z = Q 2 / s ̂ → 1 $$ z={Q}^2/\hat{s}\to 1 $$ at general subleading powers in the (1 − z) expansion.
