Flavor-Changing Top-Quark Decay Within The Minimal Supersymmetric Standard Model

We present the results of the gluino and scalar quark contribution to the flavor-changing top quark decay into a charm quark and a photon, gluon, or a Z(0) boson within the minimal supersymmetric standard model. We include the mixing of the scalar partners of the left- and right-handed top quark. This mixing has several effects, the most important of which is to greatly enhance the cZ decay mode for large values of the soft SUSY-breaking scalar mass m(s) and to give rise to a GIM-like suppression in the c gamma mode for certain combinations of parameters.
