SANCnews: Sector 4f, Charged Current
Abstract
In this paper we describe the implementation of the charged current decays of the kind t --> b l+ nul (gamma) into framework of SANC system. All calculations are done taking into account one-loop electroweak correction in the Standard Model. The emphasis of this paper is done on the presentation of numerical results. Various distributions are produced by means of a Monte Carlo integrator and event generator. Comparison with the results of CompHEP and PYTHIA packages are presented for the Born and hard photon contributions. The validity of the cascade approximation at one-loop level is also studied.
