Lepton flavor violating decay of SM-like Higgs boson in a radiative neutrino mass model

The lepton flavor violating decay of the Standard Model-like Higgs boson (LFVHD) is discussed in the framework of the radiative neutrino mass model built in [K. Nishiwaki, H. Okada, and Y. Orikasa, Phys. Rev. D 92, 093013 (2015)]. The branching ratio (BR) of the LFVHD is shown to reach 10(-5) in the most interesting region of the parameter space shown in [K. Nishiwaki, H. Okada, and Y. Orikasa, Phys. Rev. D 92, 093013 (2015)]. The dominant contributions come from the singly charged Higgs mediations, namely, the coupling of h(2)(+) with exotic neutrinos. Furthermore, if the doubly charged Higgs boson is heavy enough to allow the mass of h(2)(+) around 1 TeV, the mentioned BR can reach 10(-4). In addition, we obtain that the large values of Br(h -> mu tau). lead to very small ones of Br(h -> e tau), much smaller than the various sensitivities of current experiments.
