We study some New Physics effects on the hadronic decays of the Top quark, like t\ensuremath→bbc, and on a forward-backward-like CP even asymmetry At constructed in such a way that it is zero in the standard model (SM). We find that an anomalous right-handed contribution of the effective tbW vertex may induce an asymmetry At of the order of 20%. A light W^\ensuremath' boson with pure right-handed couplings tdW^\ensuremath' may induce an asymmetry At of the same order of magnitude.
