摘要：

The next-to-leading corrections of leading-log asymptotic freedom are determined in the known infrared (IR) regularization schemes. On- and off-shell calculation leads to different answers; the n-dimensional regularization of IR and mass singularities agrees with the on-shell results. The non-log corrections in Drell-Yan processes are important for Q2 ≲ 103 GeV2. © 1979.
