New Physics effects on hadronic decay asymmetries of the Top quark

Abstract

We study some New Physics effects on the hadronic decays of the Top quark, like t-> b bbar c, and on a forward-backward-like CP even asymmetry A_t constructed in such a way that it is zero in the SM. We find that an anomalous right-handed contribution of the effective tbW vertex may induce an asymmetry A_t of the order of 20 %. A light W' boson with pure right handed couplings tdW' may induce an asymmetry A_t of the same order of magnitude.
