Electroweak-correction effects in gauge-boson pair production at the LHC

We have studied the effect of one-loop logarithmic electroweak radiative corrections on WZ and Wγ production processes at the LHC. We present analytical results for the leading-logarithmic electroweak corrections to the corresponding partonic processes d̄u → WZ,Wγ. Using the leading-pole approximation we implement these corrections into Monte Carlo programs for pp → lνll l̄′, lνlγ. We find that electroweak corrections lower the predictions by 5–20% in the physically interesting region of large transverse momentum and small rapidity separation of the gauge bosons.
