摘要：

In this paper, we calculate the rare top quark decay t -> ch in a supersymmetric extension of the Standard Model where baryon and lepton numbers are local gauge symmetries. Adopting reasonable assumptions on the parameter space, we find that the branching ratios of t -> ch can reach 10(-3), which could be detected in the near future.
