Charged lepton flavor violation (CLFV) represents a clear new physics (NP) signal beyond the standard model (SM). In this work, we investigate CLFV processes l₉^-l₈^- 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 l₉^-l₈^- with the sensitive parameters will be intuitively analyzed. Considering the SM-like Higgs boson mass and the muon anomalous dipole moment (MDM) within 4, 3, and 2 regions, we discuss the corresponding constraints on the relevant parameter space of the model.
