Description
In this talk we discuss the decays of the top quark, focusing on the flavor-changing neutral currents (FCNC) modes, as well as the modes with multilepton final states. The FCNC modes are very suppressed within the Standard Model (SM) of electroweak interactions, but could be enhanced in extension of the SM, such as the two-Higgs doblet model and Supersymmetry. The decay modes with multi-lepton final states, such as t->b W l+ l-, could have a branching ratio well above the expected Br's for FCNC modes within the SM. We also discuss the expected BR's that could be studied at the LHC at CERN.
