摘      要：In a few years, the COMET experiment at J-PARC and the Mu2e experiment at Fermilab will probe the µ − e conversion rate in the vicinity of O(10−17) for an Al target with high experimental sensitivity. Within the framework of the minimal supersymmetric extension of the Standard Model with local B − L gauge symmetry (B-LSSM), we analyze the lepton flavor violating (LFV) process of µ−e conversion in nuclei. Considering the constraint of the experimental upper limit of the LFV rare decay µ → eγ, the µ − e conversion rates in nuclei within the B-LSSM can achieve O(10−12), which is 5 orders of magnitude larger than the future experimental sensitivity at the Mu2e and COMET experiments and may be detected in the near future. © 2022, CC BY.
