Large signal of $h\to \mu \tau$ within the constraints of $e_i\to e_j\gamma$ decays in the 3-3-1 model with neutral leptons

Abstract

In the framework of the 3-3-1 model with neutral leptons, we have investigated the lepton-flavor-violating sources based on the Higgs mass spectrum which has two neutral Higgses identitied with corresponding ones in the Two-Higgs-Doublet model (THDM). On the $13\mathrm{TeV}$ scale of the LHC, we point out the parameter space regions where the experimental limits of $e_i\to e_j\gamma$ decays are satisfied. These regions depend heavily on the mixing of exotic leptons but are predicted to have large $h_1^0\to \mu \tau$ signals. We also show that $\mathrm{Br}(h_1^0\to \mu \tau )$ can reach a value of $10^{-4}$.
