Abstract: 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 after introducing new gauginos and right-handed neutrinos. In this model, the branching ratios of Z→li±lj are 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.
