Detection of heavy charged Higgs bosons at future Linear Colliders via $τ^-\barν_τH^+$ 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 $\tanβ$ in the $M_{H^\pm}\gsim \sqrt s/2$ mass region
