Contribution

It provides updated predictions for m_t and m_W in supersymmetric models, incorporating comprehensive experimental and theoretical information.

Findings

Predictions for m_t and m_W are highly compatible with experimental values.

Supersymmetric models show improved agreement over the Standard Model.

Remaining uncertainties are small, indicating precise predictions.

Abstract

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, m_t, and the W boson mass, m_W. We find that the supersymmetric predictions for both m_t and m_W, 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.
