摘要We study transverse-momentum-dependent (TMD) gluon distributions and related factorization theorems for gluon-initiated semi-inclusive processes at hadron colliders. Gauge-invariant TMD gluon distributions are introduced, and their relations to the integrated (Feynman) parton distributions are established when the transverse momentum is large. Through explicit calculations, soft-collinear factorization is verified at one-loop order for scalar particle ( e. g. Higgs) production. Summation over large double logarithms is performed through solving Collins-Soper equation. We reproduce the known result in the limit that the transverse momentum of the scalar is large.
