Abstract
In the Higgs Triplet Model and the neutrinophilic Two-Higgs-Doublet Model the observed neutrinos obtain mass from a vacuum expectation value which is much smaller than the vacuum expectation value of the Higgs boson in the Standard Model. Both models contain a singly charged Higgs boson (H±) whose Yukawa coupling is directly related to the neutrino mass (i.e. a "neutrinophilic charged Higgs"). The partial decay widths of H± into a charged lepton and a neutrino (H± to ℓ± ν) depend identically on the neutrino masses and mixings in the two models. We quantify the impact of the recent measurement of sin2 2θ13, which plays a crucial role in determining the magnitude of the branching ratio of H± to e± ν for the case of a normal neutrino mass ordering if the lightest neutrino mass m0 < 10-3 eV. We also discuss the sizeable dependence of H± to μ± ν and H± to τ± ν on sin2θ23, which would enable information to be obtained on sin2θ23 and the sign of Δ m231 if these decays are measured. Such information would help neutrino oscillation experiments to determine the CP-violating phase δ.
