We present a general purpose Monte Carlo program for the calculation of any infrared safe observable in W γ and Zγ production at hadron colliders at nextto-leading order in α s . We treat the leptonic decays of the W and Z-boson in the narrow-width approximation, but retain all spin information via decay angle correlations. The effect of anomalous triple gauge boson couplings is investigated and we give the analytical expressions for the corresponding amplitudes. Furthermore, we propose a way to study the effect of anomalous couplings without introducing the ambiguity of form factors.

W + W − production is one of the golden channels for testing the Standard Model as well for searches beyond the Standard Model. We discuss many new subleading processes for inclusive production of W + W − pairs generally not included in the literature so far. We focus on photon-photon induced processes. We include elastic-elastic, elastic-inelastic, inelastic-elastic and inelastic-inelastic contributions. We also calculate the contributions with resolved photons including the partonic substructure of the virtual photon. Predictions for the total cross section and differential distributions in W -boson rapidity and transverse momentum as well as W W invariant mass are presented. The γγ components constitute only about 1-2 % of the inclusive W + W − cross section but increases up to about 10 % at large W ± transverse momenta, and are even comparable to the dominant qq component at large M W W , i.e. are much larger than the gg → W + W − one.
