Flavour changing top decays in supersymmetric extensions of the standard model

G. M. de Divitiis, R. Petronzio, L. Silvestrini

Flavour changing top decays $t\to c{Z}^0,t\to cg$ and $t\to c\gamma$ are predicted with invisible rates within the standard model and may represent a window on new physics. We cons…
