Lepton-number-violating decays of singly-charged Higgs bosons in the type-(Ⅰ+Ⅱ) seesaw model

  • The lepton-number-violating decays of singly-charged Higgs bosons H±are investigated in the minimal type-(Ⅰ+Ⅱ) seesaw model with oneSU(2)LHiggs triplet Δ and one heavy Majorana neutrino N1at the TeV scale. We find that the branching ratios B (H+→l+αν) (for α=e, μ, τ) depend not only on the mass and mixing parameters of three light neutrinos νi(fori=1,2,3) but also on those of N1. Assuming that the mass of N1lies in the range of 200 GeV to 1 TeV, we figure out the generous interference bands for the contributions of νiandN1to B(H+→l+αν). We illustrate some salient features of such interference effects by considering three typical mass patterns of νi, and show that the relevant MajoranaCP-violating phases can affect the magnitudes of B (H+→l+αν) in this parameter region.

    Lepton-number-violating decays of singly-charged Higgs bosons in the type-(Ⅰ+Ⅱ) seesaw model

      Corresponding author:REN Ping,

      Abstract:

      The lepton-number-violating decays of singly-charged Higgs bosons H±are investigated in the minimal type-(Ⅰ+Ⅱ) seesaw model with oneSU(2)LHiggs triplet Δ and one heavy Majorana neutrino N1at the TeV scale. We find that the branching ratios B (H+→l+αν) (for α=e, μ, τ) depend not only on the mass and mixing parameters of three light neutrinos νi(fori=1,2,3) but also on those of N1. Assuming that the mass of N1lies in the range of 200 GeV to 1 TeV, we figure out the generous interference bands for the contributions of νiandN1to B(H+→l+αν). We illustrate some salient features of such interference effects by considering three typical mass patterns of νi, and show that the relevant MajoranaCP-violating phases can affect the magnitudes of B (H+→l+αν) in this parameter region.
