TIFR/TH/95-08CHARGED HIGGS BOSON SEARCH AT THE TEV ATRON UPGRADE USING TAU POLARIZATION Sreerup Raychaudhuri and D.P.Roy 1Theoretical Physics Group Tata Institute of Fundamental Research Homi Bhabha Road,Bombay 400005,India ABSTRACT We explore the prospect of charged Higgs boson search in top quark decay at the Tevatron collider upgrade,taking advantage of the opposite states of τpolarization resulting from the H ±and W ±decays.Methods of distinguishing the two contributions in the inclusive 1-prong hadronic decay channel of τare suggested.The resulting signature and discovery limit of H ±are presented for
the Tevatron upgrade as well as the Tevatron ?and the Ditevatron options.March 1995
