Charged Higgs bosons at the Superconducting Super Collider

We study techniques for discovering at the Superconducting Super Collider (SSC) a charged Higgs boson of a two-doublet Higgs sector in the decay t→H⁺b, for a variety of top-quark and charged-Higgs-boson masses. tt̄ events are selected by demanding a high-pT lepton and a tagged b jet. One technique is to search for an excess of τ leptons from H⁺ decays. For tanβ≡v₂v₁0.5, this technique is usually viable, even for a fraction of the expected SSC yearly luminosity (depending upon mₜ and m_H⁺). Techniques for approximately determining the H⁺ mass in this mode are discussed. We also demonstrate that for 0.1tanβ1.5 a peak in the two-jet mass distribution resulting from H⁺→cs̄ can be found, and a precise H⁺ mass determination is possible even in a fraction of an SSC year, provided B(t→H⁺b) is not too small.
