Charged Higgs phenomenology in the lepton-specific two Higgs doublet model
- Ottawa-Carleton Institute for Physics, Carleton University, Ottawa K1S 5B6 (Canada)
We study the ''lepton-specific'' two Higgs doublet model, in which one doublet {phi}{sub l} gives mass to charged leptons and the other {phi}{sub q} gives mass to both up- and down-type quarks. We examine the existing experimental constraints on the charged Higgs boson mass and the parameter tan{beta}{identical_to}<{phi}{sub q}{sup 0}>/<{phi}{sub l}{sup 0}>. The most stringent constraints come from LEP-II direct searches and lepton flavor universality in {tau} decays. The former yields M{sub H{sup {+-}}}{>=}92.0 GeV; the latter yields two allowed regions 0.61tan{beta} GeV{<=}M{sub H{sup {+-}}}{<=}0.73tan{beta} GeV or M{sub H{sup {+-}}}{>=}1.4tan{beta} GeV, and excludes parameter regions beyond the LEP-II bound for tan{beta} > or approx. 65. We present the charged Higgs decay branching fractions and discuss prospects for charged Higgs discovery at the LHC in this model.
