摘要：

We present the complete order alpha(s)2 contribution to the Drell-Yan coefficient function in the DIS scheme. Its effect on the corresponding K-factor is studied and a comparison is made with the K-factor computed in the MSBAR scheme presented previously. Predictions are given for W- and Z-production at current as well as future large hadron colliders. The difference between the cross sections obtained by the two schemes is of the same size as the one obtained from the variation of the cross section caused by a big change in the mass factorization and renormalization scale.
