Description
Electroweak one-loop corrections to on-shell WW, ZZ, WZ and gamma-gamma production at the LHC are presented, explicitly taking into account the full vector-boson mass dependence. Leptonic decays and the associated weak corrections are included in our analysis. For the WW-case the dominant logarithmic terms relevant for the high energy behaviour are evaluated in two-loop approximation. Starting from these fixed-order results, a straight forward procedure is motivated to combine electroweak corrections with state-of-the-art MonteCarlo predictions. To illustrate the approach, the results of an implementation into HERWIG++ are presented.
