摘要：

We report on the implementation of an interface between the SANC generator framework for Drell-Yan hard processes, which includes next-to-leading order elect roweak (NILO EW) corrections, and the Herwig++ and Pythia8 QGD parton shower Monte Carlos. A special aspect of this implementation is that the initial-state shower evolution in both shower generators has been augmented to handle the case of an incoming photon-in-a-proton, diagrams for which appear at the NLO EW level. The difference between shower algorithms leads to residual differences in the relative corrections of 2-3% in the p(T)(mu) distributions at p(T)(mu) greater than or similar to 50 GeV (where the NLO EW correction itself is of order 10%).
