Abstract：
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 nd that the branching ratios of t→ch can reach 10-3, which could be detected in the near future.
