  We present a detailed study of the charged current Drell-Yan process, which
includes the exact O(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.
