摘　　要：In the framework of the 3-3-1 model with neutral leptons,we investigate lepton-flavor-violating sources based on the Higgs mass spectrum,which has two neutral Higgs identified with the corresponding ones of the two-Higgs-doublet model.We note that at the 13TeV scale of the LHC,the parameter space regions satisfy the experimental limits of e_(i)→e_(j)γecays.These regions depend heavily on the mixing of exotic leptons but are predicted to have large h_(1)^(0)→μτsignals.We also show that Br(h_(1)^(0)→μτ)can reach a value of 10^(-4).
