Theoretical Expectations in Radiative Top Decays
Abstract
Description
We summarize the Standard Model predictions for the three-body decays of the top quark t->WbX, where X = Z,H,g or gamma. Because of strong phase space suppression, we find that the branching ratios for the Z and H final states are of order a few times 10^{-7}, rendering them invisible at Tevatron Run II. On the other hand, the decays to g and gamma are suppressed only by the expected factor of alpha_s or alpha_{em}.
