摘要：
We derive stringent limits on neutrinophilic two-Higgs-doublet models from low-energy observables after the discovery of the Higgs boson and of the mixing angle θ13. These decays can constrain the plane spanned by mH±, the mass of the new charged Higgs, and v2, the vacuum expectation value of the new neutrinophilic scalar doublet. Lepton flavor conserving decays are not able to set meaningful bounds, since they depend strongly on the unknown neutrino absolute mass scale. On the other hand, loop induced lepton flavor violating decays, such as μ → eγ, μ → 3e or μ → e in nuclei are currently responsable for the best limits today. If v2 ≲ 1 (0.1) eV we get mH± ≳ 250 (2500) GeV at 90% CL. In the foreseen future these limits can improve by at least a factor of 100.
