$Z\to l_i^{\pm }{l}_j^{\mp }$ processes in the BLMSSM

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 $Z\to l_i^{\pm }{l}_j^{\mp }$ after introducing the new gauginos and the right-handed neutrinos. In this model, the branching ratios of $Z\to l_i^{\pm }{l}_j^{\mp }$ are around ($10^{-8}\sim 10^{-10}$), which approach the present experimental upper bounds. We hope that the branching ratios for these CLFV processes can be detected in the near future.
