摘要：

The O(gs2) quark-gluon correction which might invalidate the Drell-Yan formalism for ppl+l-+X, is studied in detail. It is shown that if scale violations in the parton densities are taken into account this correction is small in the whole kinematic region. Also, the rapidity dependence is not significantly affected. © 1979 The American Physical Society.
