Lepton-flavor violating decays of neutral Higgs to muon and tauon in supersymmetric economical 3-3-1 model

Abstract

We investigate Lepton-Flavor Violating (LFV) decays of Higgs to muon-tau in the supersymmetric economical 3-3-1 (SUSYE331) model. In the presence of flavor mixing in sleptons {mu,tau} and large values of v/v', the ratio of Br(H -->tau^+mu^-)/Br(H -->tau^+tau^-) can reach to non-negligible values O(10^{-3}), as in many known SUSY models. We predict that for the Standard Model Higgs boson, the LHC may detect its decay to muon and tauon. We also investigate the asymmetry between left and right LFV values of corrections and prove that the LFV effects are dominated by the left FLV term, which is O(10^3) times larger than the right LFV term in the limit of small values of |μ_ρ|/m_SUSY. The contributions of Higgs-mediated effects to the decay tau --> mu mu mu are also discussed.
