摘要：

The importance of the lowest-order non-log corrections to leading-log asymptotic freedom (AF) is investigated in pp-initiated Drell-Yan μ-pair production. In the present Q2 ranges the order αs qq corrections surmount DY by a factor 3-5 whereas the analogous qg corrections do not invalidate the AF leading-log approximation. © 1979.
