Abstract

In the framework of the flipped 3-3-1 model introduced recently [1], the lepton-flavor-violating (LFV) decay $μ \to 3 e$ was predicted to have a large branching ratio (Br) close to the recent experimental limit. We will show that the Br of LFV decays of the standard-model-like (SM-like) Higgs boson decays (LFVHD) Br $(h \to e_{a} e_{b})$ may also be large. Namely, the Br $(h \to μτ, e τ)$ can reach values of $O (1 0^{- 4}) - O (1 0^{- 5})$ , which will reach the upcoming experimental sensitivities. On the other hand, for LFV decays of charged leptons (cLFV) $(e_{b} \to e_{a} γ)$ , the branching ratios are well below experimental bounds.
