Logarithmic electroweak corrections to gauge-boson pair production at the LHC

Abstract

We have studied the effects of the complete logarithmic electroweak O ( α ) corrections on the production of vector-boson pairs WZ, ZZ, and WW at the LHC. These corrections are implemented into a Monte Carlo program for p p → 4 f ( + γ ) with final states involving four or two leptons using the double-pole approximation. We numerically investigate purely leptonic final states and find that electroweak corrections lower the predictions by 5–30% in the physically interesting region of large di-boson invariant mass and large angle of the produced vector bosons.
