It presents the first complete calculation of electroweak corrections to W-boson hadroproduction at finite p_T, including various production channels and photon contributions.

Findings

Electroweak corrections significantly affect W-boson cross sections.

Predictions align with experimental conditions at Tevatron and LHC.

Theoretical uncertainties are estimated and discussed.

Abstract

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.
