摘要: We calculate the effects of next-to-leading order perturbative QCD as well quark transverse motion and off-shellness on Drell-Yan process cross section. By studying s{yields}{infinity} behavior section in these approaches, we find that intrinsic-k{sub T} parametrize those higher twists. In particular, partons generates part K-factor type corrections to leading Higher-twist contributions p{sub T}-spectrum pairs are found be large for presently accessible energies. The evolution distribution with hard scale is also studied.
