Associated production of a Higgs boson with tau sleptons in the CP violating MSSM at future e^+ e^- colliders

Abstract

We investigate the production of the lightest neutral Higgs boson in association with tau sleptons in the CP violating minimal supersymmetric standard model (MSSM) at future high-energy $e^{+}{e}^{-}$ linear colliders. In parameter space of the constrained MSSM, the production cross section of $e^{+}{e}^{-}\to h^0{\tilde{\tau }}_1^{+}{\tilde{\tau }}_1^{-}$ can be very substantial at high energies. This process would provide a new production mechanism of neutral Higgs bosons and open a window to probe the Higgs-stau coupling and some soft supersymmetric breaking parameters at next linear colliders.
