Lepton flavor violating decays of the SM-like Higgs boson $hrightarrow e_ie_j$, and $e_i rightarrow e_j, gamma $ in a flipped 3-3-1 model


Abstract in English

In the framework of the flipped 3-3-1 model introduced recently [1], the lepton-flavor-violating (LFV) decay $mu rightarrow 3e$ 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$(hrightarrow e_ae_b)$ may also be large. Namely, the Br$(hrightarrow mutau,etau)$ can reach values of $mathcal{O}(10^{-4})-mathcal{O}(10^{-5})$, which will reach the upcoming experimental sensitivities. On the other hand, for LFV decays of charged leptons (cLFV) $(e_brightarrow e_agamma)$, the branching ratios are well below experimental bounds.
