Charged Higgs phenomenology in the flipped two-Higgs-doublet model

We study the phenomenology of the charged Higgs boson in the flipped two-Higgs-doublet model, in which one doublet gives mass to up-type quarks and charged leptons, and the other gives mass to down-type quarks. We present the charged Higgs branching ratios and summarize the indirect constraints. We extrapolate existing LEP searches for H+H- and Tevatron searches for t (t) over bar t -> H(+)b into the flipped model and extract constraints on MH+ and the parameter tan beta. We finish by reviewing existing LHC charged Higgs searches and suggest that the LHC reach in this model could be extended for charged Higgs masses below the tb threshold by considering t (t) over bar with t -> H(+)b and H+ -> q (q) over bar', as has been used in Tevatron searches.
