Abstract
The computation of the Oð sÞ QCD corrections to the cross sections for W` production in hadronic collisions is presented. We consider the case of real photons in the final state, but include full leptonic decays of the W. Numerical results for the LHC and the Tevatron are obtained through a parton level Monte Carlo based on the structure of the VBFNLO program, allowing an easy implementation of general cuts and distributions. We show the dependence on scale variations of the integrated cross sections and provide evidence of the fact that next-to-leading-order QCD corrections strongly modify the leading order predictions for observables at the LHC both in magnitude and in shape.
