Abstract

The lepton flavor violating (LFV) decays h, Z→ e_b e_a , and e_b→ e_a γ are discussed in a class of general 3-3-1 models adding heavy neutral leptons and singly charged Higgs bosons to accommodate experimental data of neutrino oscillation and (g-2)_ea anomalies of charged leptons through the inverse seesaw mechanism. We show that the models with the minimal number of inverse seesaw neutrinos cannot reach the 1σ range of (g-2)_μ data due to the experimental upper bounds on decay rates of (τ→ μγ) and (μ→ e γ). Features of LFV decays are presented in detail, focusing on the regions of parameter space satisfying the 1σ ranges of (g-2)_e,μ data.
