摘要：

The decays t-->cV (V = gamma,g, or Z) induced through loop processes are calculated in the minimal supersymmetric model. We find that these new contributions can enhance the standard model branching fractions by as much as 3-4 orders of magnitude, i.e., B(t-->cg) approximately 10(-6), B(t-->cZ) approximately 10(-8), and B(t-->Cgamma) approximately 10(-8) for favorable values of the parameters.
