摘　　要：In a supersymmetric extension of the Standard Model（SM） where baryon and lepton numbers are local gauge symmetries（BLMSSM）, we investigate the charged lepton flavor violating（CLFV） processes Z→li^±lj^ jafter introducing new gauginos and right-handed neutrinos. In this model, the branching ratios of Z→li^±lj^ jare around（10^-8–10^-10）, which approach the present experimental upper bounds. We hope that the branching ratios for these CLFV processes can be detected in the near future.In a supersymmetric extension of the Standard Model（SM） where baryon and lepton numbers are local gauge symmetries（BLMSSM）, we investigate the charged lepton flavor violating（CLFV） processes Z→li^±lj^ jafter introducing new gauginos and right-handed neutrinos.
