A Monte Carlo simulation of decays under the SANC project

The library of Monte Carlo programs for simulation of two particle leptonic and quark decays of the W, Z and H (Higgs) bosons with single bremsstrahlung photon emission as a part of the SANC system is described. The QED and EW O(α) radiative corrections are implemented. The decay amplitudes are numerically evaluated using the Kleiss–Stirling spinor method. Comparisons with KORALZ and PHOTOS are also presented (Comput. Phys. Commun. 66 (1991) 113; Comput. Phys. Commun. 79 (1994) 503).
