Abstract

The lepton flavor violating (LFV) decays h,Z→ebea, and eb→eaγ 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→eγ). 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. Published by the American Physical Society 2024
