Testing the MSSM with the Mass of the W Boson

TL;DR

This paper provides a comprehensive and precise calculation of the W boson mass within the MSSM, incorporating full one-loop and two-loop corrections, and compares the theoretical prediction with experimental data.

Contribution

It offers the most accurate MSSM prediction of M_W by including all relevant higher-order corrections and phase dependencies, enhancing the precision of supersymmetric tests.

Findings

The MSSM prediction for M_W aligns with experimental measurements within uncertainties.

Complex phases in the scalar quark sector significantly influence the M_W prediction.

Higher-order corrections improve the theoretical accuracy of MSSM W boson mass calculations.

Abstract

We review the currently most accurate evaluation of the W boson mass, M_W, in the Minimal Supersymmetric Standard Model (MSSM). It consists of a full one-loop calculation, including the complex phase dependence, all available MSSM two-loop corrections as well as the full Standard Model result. We analyse the impact of the phases in the scalar quark sector on M_W and compare the prediction for M_W based on all known higher-order contributions with the experimental results.
