Resumen:
We present a general purpose MonteCarlo program for the calculation of any infrared safe observable in Wγ and Zγ production at hadron colliders at next-to-leading order in αs. 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.
