Detection of Charged MSSM Higgs Bosons at CERN LEP-II and NLC

Abstract

We study the possibility of detecting the charged Higgs bosons predicted in the Minimal Supersymmetric Standard Model $(H^\pm)$, with the reactions $e^{+}e^{-}\to τ^-\bar ν_τH^+, τ^+ν_τH^-$, using the helicity formalism. We analyze the region of parameter space $(m_{A^0}-\tanβ)$ where $H^\pm$ could be detected in the limit when $\tanβ$ is large. The numerical computation is done for the energie which is expected to be available at LEP-II ($\sqrt{s}=200$ GeV) and for a possible Next Linear $e^{+}e^{-}$ Collider ($\sqrt{s}=500$ GeV).
