Precision SUSY Physics

Abstract

We review the theoretical status and the future perspectives of the most important electroweak precision observables in the MSSM. This comprises the mass of the W boson, M_W, the effective leptonic mixing angle, sin^2(theta_eff), the mass of the lightest MSSM Higgs boson, m_h, and the anomalous magnetic moment of the muon, a_\mu. The impact of the parametric uncertainties from the experimental errors of the input parameters is studied, and an estimate for the remaining uncertainties from unknown higher-order corrections is given. The need for future improvements in the theory predictions is investigated.Comment: 6 pages, invited talk at "Loops & Legs in Quantum Field Theory 2004", Zinnowitz, Germany, April 200
