Abstract
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. tt¯ 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≡v2v1≳0.5, this technique is usually viable, even for a fraction of the expected SSC yearly luminosity (depending upon mt and mH+). Techniques for approximately determining the H+ mass in this mode are discussed. We also demonstrate that for 0.1≲tanβ≲1.5 a peak in the two-jet mass distribution resulting from H+→cs¯ 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.
