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. ttBAR events are selected by demanding a high-p(T) lepton and a tagged b jet. One technique is to search for an excess of tau leptons from H+ decays. For tanbeta=v2/v1 greater than or similar to 0.5, this technique is usually viable, even for a fraction of the expected SSC yearly luminosity (depending upon m(t) and m(H+)). Techniques for approximately determining the H+ mass in this mode are discussed. We also demonstrate that for 0.1 less than or similar to tanbeta less than or similar to 1.5 a peak in the two-jet mass distribution resulting from H+ --> csBAR 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.
