Electroweak corrections and anomalous triple gauge-boson couplings inW+W−andW±Zproduction at the CERN LHC

We have analyzed the production of $WZ$ and $WW$ vector-boson pairs at the LHC. These processes give rise to four-fermion final states, and are particularly sensitive to possible nonstandard trilinear gauge-boson couplings. We have studied the interplay between the influence of these anomalous couplings and the effect of the complete logarithmic electroweak $\mathcal{O}(\alpha )$ corrections. Radiative corrections to the standard model processes in double-pole approximation and nonstandard terms due to trilinear couplings are implemented into a Monte Carlo program for $pp\to 4f(+\gamma )$ with final states involving four or two charged leptons. We numerically investigate purely leptonic final states and find that electroweak corrections can fake new-physics signals, modifying the observables by the same amount and shape, in kinematical regions of statistical significance.
