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 → l ± i l ∓ j after introducing new gauginos and right-handed neutrinos. In this model, the branching ratios of Z → l ± i l ∓ j 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.

“…In our previous works, Br(µ → eγ) < 5.7 × 10 −13 , Br(µ → 3e) < 1.0 × 10 −12 and Br(Z → eµ) < 7.5 × 10 −7 [24,29,59] are strict constrains for our parameter space.…”

“…In our previous works, Brðμ→eγÞ<5.7×10 −13 , Brðμ→ 3eÞ<1.0×10 −12 , and BrðZ →eμÞ<7.5×10 −7 [24,29,55] are strict constraints for our parameter space. In this work, we take the same parameter space satisfying the constraints of processes μ → eγ; μ → 3e, and Z → eμ.…”
