摘要：

The remarkable agreement with experiment of first order QCD predictions for leptoproduction suggest that nonleading corrections are small. However, existing calculations of second order corrections indicate this is not the case. In this note we investigate the sensitivity of nonleading log corrections to the choice of renormalisation procedure. We derive tests of QCD which are insensitive to this choice. We also discuss how the remaining predictions may be made less sensitive to the effect of nonleading terms. © 1979.
