Abstract The current status of electroweak precision observables in the Minimal Supersymmetric Standard Model (MSSM) is reviewed. We focus in particular on the W boson mass, M W , the effective leptonic weak mixing angle, sin 2 θ eff , the anomalous magnetic moment of the muon, ( g - 2 ) μ , and the lightest CP -even MSSM Higgs boson mass, m h . We summarize the current experimental situation and the status of the theoretical evaluations. An estimate of the current theoretical uncertainties from unknown higher-order corrections and from the experimental errors of the input parameters is given. We discuss future prospects for both the experimental accuracies and the precision of the theoretical predictions. Confronting the precision data with the theory predictions within the unconstrained MSSM and within specific SUSY-breaking scenarios, we analyse how well the data are described by the theory. The mSUGRA scenario with cosmological constraints yields a very good fit to the data, showing a clear preference for a relatively light mass scale of the SUSY particles. The constraints on the parameter space from the precision data are discussed, and it is shown that the prospective accuracy at the next generation of colliders will enhance the sensitivity of the precision tests very significantly.

- Fully covering the MSSM Higgs sector at the LHC (2015, background): “If one allows for an uncertainty of a say 3 GeV in the determination of the h mass in the MSSM, from unknown higher order contributions for instance [41–44], the situation is acceptable if the h mass is confined in the range 122 GeV <∼Mh<∼ 128 GeV.”
- The Muon Magnetic Moment and Supersymmetry (2006, background): “Moreover, in contrast to many other scenarios for physics beyond the SM, the minimal supersymmetric standard model (MSSM) is a weakly coupled, renormalizable gauge theory [26], such that quantum effects are computable and welldefined, and it has survived many non-trivial electroweak precision tests ”
