Charged Higgs boson search at the Tevatron upgrade using Tau polarization

Abstract

We explore the prospect of a charged Higgs boson search in top quark decay at the Tevatron collider upgrade, taking advantage of the opposite states of τ polarization resulting from the H^± and W^± decays. Methods of distinguishing the two contributions in the inclusive 1-prong hadronic decay channel of τ are suggested. The resulting signature and discovery limit of H^± are presented for the Tevatron upgrade as well as the Tevatron* and the Ditevatron options.
