Charged lepton flavor violation in the B−L symmetric SSM

Charged lepton flavor violation (CLFV) represents a clear new physics (NP) signal beyond the standard model (SM). In this work, we investigate CLFV processes lⱼ^-→lᵢ^-γ utilizing mass insertion approximation (MIA) in the minimal supersymmetric extension of the SM with local B-L gauge symmetry (B-L SSM). The MIA method can provide a set of simple analytic formulas for the form factors and the associated effective vertices, so that the movement of the CLFV decays lⱼ^-→lᵢ^-γ with the sensitive parameters will be intuitively analyzed. Considering the SM-like Higgs boson mass and the muon anomalous dipole moment (MDM) within 4σ, 3σ, and 2σ regions, we discuss the corresponding constraints on the relevant parameter space of the model.
