Precision Electroweak Calculation of the Charged Current Drell-Yan Process

We present a detailed study of the charged current Drell-Yan process, which includes the exact order alpha electroweak corrections properly matched with leading-log effects due to multiple-photon emission, as required by the experiments at the Tevatron and the LHC. Numerical results for the relevant observables of single W boson production at hadron colliders are presented. The impact of the radiative corrections and of some sources of theoretical uncertainty is discussed in detail. The calculation has been implemented in the new version of the event generator HORACE, which is available for precision simulations of the charged current Drell-Yan process.
