Measuring Higgs Coupling to Tau-Leptons at Future e+ e- Colliders

Abstract

We perform a complete simulation of the process $e^{+}{e}^{-}\to {\tau }^{+}{\tau }^{-}\nu \bar{\nu }$, where $\nu$ can be an electron, muon or tau neutrino, in the context of a general Higgs coupling to $\tau$ leptons. We analyse various kinematical distributions and obtain the sensitivity regions in the parameter space that can be explored at a future $e^{+}{e}^{-}$ collider. In particular, inclusion of $W$ boson fusion enhances the sensitivity significantly.
