We present a factorization theorem of the partonic Drell-Yan off-diagonal processes gq¯qg→γ∗+X in the kinematic threshold regime z=Q2/ŝ→1 at general subleading powers in the (1 − z) expansion. Focusing on the first order of the expansion (next-to-le... Read More about Threshold factorization of the Drell-Yan quark-gluon channel and two-loop soft function at next-to-leading power.
