摘要：
We calculate the full one-loop electroweak radiative corrections to the cross section of single W-boson inclusive hadroproduction at finite transverse momentum (p(T)). This includes the O(alpha) corrections to W + j production, the O(alpha(s)) corrections to W + gamma production, and the tree-level contribution from W + j photoproduction with one direct or resolved photon in the initial state. We present the integrated cross section as a function of a minimum-p(T) cut as well as the p(T) distribution for the experimental conditions at the Fermilab Tevatron and the CERN LHC and estimate the theoretical uncertainties.
