Γ(Z→ bb) to NNLO in the MSSM — •Ralf Paulig — TTP Karlsruhe

The inclusive decay rate of a Z boson into bottom quarks is computed in the framework of supersymmetric QCD to NNLO accuracy. We apply asymptotic expansion to obtain analytical results for different hierarchies in the supersymmetric particle specturm. The numerical implications are briefly discussed for the SPS benchmark points.
