Flavour changing top quark decay within the minimal supersymmetric standard model

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

We present the results of the gluino and scalar quarks contribution to the flavour changing top quark decay into a charm quark and a photon, gluon or a Z0Z^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 are to greatly enhance the c Z decay mode for large values of the soft SUSY breaking scalar mass mSm_S\ and to give rise to a GIM--like suppresion in the c γ\gamma\ mode for certain combinations of parameters.
