Abstract

In order to determine the fundamental MSSM parameters M₁, M₂, μand tanβthe tau polarization from stau decays can be explored as a `bridge' between the gaugino/higgsino and the stau sector in particular in the high tanβrange. Even in the case of high tanβan accuracy of δ(tanβ)≈ 5% with an simultanous determination of A_τ is possible without assuming a specific SUSY breaking scheme.
