Predictions for mt and MW in minimal supersymmetric models

Using a frequentist analysis of experimental constraints within two versions of the minimal supersymmetric extension of the standard model, we derive the predictions for the top quark mass, mt, and the W boson mass, MW. We find that the supersymmetric predictions for both mt and MW, obtained by incorporating all the relevant experimental information and state-of-the-art theoretical predictions, are highly compatible with the experimental values with small remaining uncertainties, yielding an improvement compared to the case of the standard model.
