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 $M_{H^{\pm }}\text{gsim}\sqrt{s}/2$ mass region
