Search for charged lepton flavor violation of vector mesons in the BLMSSM model

Abstract

We analyze the charged lepton flavor violating (CLFV) decays of vector mesons V→li±lj with V{φ,J/Ψ, ,ρ0,ω} in the BLMSSM model. This new model is introduced as a supersymmetric extension of the Standard Model (SM), where local gauged baryon number B and lepton number L are considered. The numerical results indicate the BLMSSM model can produce significant contributions to such two-body CLFV decays, and the branching ratios to these CLFV processes can easily reach the present experimental upper bounds. Therefore, searching for CLFV processes of vector mesons may be an effective channel to study new physics.
