Description
We investigate charged lepton flavor violating (CLFV) processes in the “neutrinophilic Higgs + seesaw model”, in which right-handed neutrinos couple only with an extra Higgs field which develops a tiny vacuum expectation value and the right-handed neutrinos also have Majorana mass. The model realizes a seesaw mechanism around TeV scale without extremely small Dirac Yukawa couplings. A phenomenological feature of the model is CLFV processes induced by loop diagrams of the charged scalar particles and heavy neutrinos. Therefore, first we constrain the model’s parameter space from the search for μ→eγ⁠. Next, we predict the branching ratios of other CLFV processes including the μ→3e⁠, μ+Al→e+Al⁠, μ+Ti→e+Ti⁠, Z→eμ⁠, Z→eτ⁠, Z→μτ⁠, h→eτ and h→μτ processes, and discuss their detectability in future experiments.
