摘要

In this addendum to T. Becher and X. Garcia i Tormo, Phys. Rev. D 88, 013009 (2013), we give results for the electroweak Sudakov corrections in gauge-boson production at large transverse momentum p(T) at proton colliders. For the results to be easily usable, we provide a simple and accurate parametrization of the corrections as a function of p(T) and the center-of-mass energy root s. Additionally, we also discuss the dependence of the electroweak corrections on the rapidity of the produced boson and comment on the complications that arise in the photon-production case due to isolation requirements.
