The O({alpha}) electroweak radiative corrections to the process pp&barpar;{r_arrow}W{sup {plus_minus}}{r_arrow}scr(l){sup {plus_minus}}{nu} (scr(l)=e,{mu}) are calculated. The O({alpha}) corrections can be decomposed into separate gauge invariant contributions to the W boson production and decay processes. Factorizing the collinear singularity associated with initial state photon radiation into the parton distribution functions, we find that initial state corrections have a significantly smaller effect than final state radiative corrections. We study in detail the effect of electroweak radiative corrections on a number of interesting observables: the W transverse mass distribution, the W to Z transverse mass ratio, the charge asymmetry of leptons in W{r_arrow}scr(l){nu} decays, as well as the W production cross section and the W to Z cross section ratio. We also investigate how experimental lepton identification requirements change the effect of the electroweak corrections. {copyright} {ital 1998} {ital The American Physical Society}
