Detection of heavy charged Higgs bosons at future Linear Colliders via $\tau^-\bar\nu_\tau H^+$ production

Abstract

We show how a statistically significant signal of heavy charged Higgs bosons of a Type II Two-Higgs Doublet (2HDM) Model produced in association with tau-neutrino pairs can be established at future $e^+e^-$ Linear Colliders (LCs) in the $H^+\to t\bar b\to 4$ jet decay channel for large $\tan\beta$ in the M_{H^\pm}\gsim \sqrt s/2 mass regionComment: 6 pages, latex, 3 figures; talk given at the International Workshop on Linear Colliders (LCWS2002), Jeju Island, Korea, 26-30 August 2002; one reference added and one correcte
