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

We study the effect of one-loop logarithmic electroweak radiative corrections on WZ and $W\gamma$ production processes at the CERN Large Hadron Collider. We present analytical results for the leading-logarithmic electroweak corrections to the corresponding partonic processes $\overline{d}\overrightarrow{u}WZ,$ $W\gamma .$ Using the leading-pole approximation we implement these corrections into Monte Carlo programs for $p\overrightarrow{p}l{\nu }_l{l}^{\prime }{l}^{\prime },$ $l{\nu }_l\gamma .$ 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.
