While the rates for associated Higgs production with neutralinos and first/second generation sleptons are rather tiny, the cross section for the production of the lightest Higgs boson $h$ with scalar $\tau$ lepton pairs can reach the femtobarn level at c.m. energies at and above 500 GeV in favorable regions of the parameter space, making this process potentially detectable at a high-luminosity $\ee$ collider, in particular in the $\gamma \gamma$ option. This would provide a determination of the $h \tilde{\tau} \tilde{\tau}$ coupling and opens up the possibility of measuring the parameter $\tan \beta$. |
