Standard Model Prediction of the Muon Anomalous Magnetic Moment

TL;DR

This paper reviews the Standard Model calculation of the muon anomalous magnetic moment, highlighting a 3.2 sigma discrepancy with experimental measurements, which suggests potential new physics beyond the Standard Model.

Contribution

It provides an updated review of the Standard Model prediction for the muon g-2 and discusses the current discrepancy with experimental data.

Findings

Discrepancy of (25.5 +- 8.0) x 10^-10 between theory and experiment

Current deviation is 3.2 standard deviations

Standard Model prediction aligns with previous estimates

Abstract

I review the present Standard Model prediction of the muon anomalous magnetic moment. The discrepancy with its experimental determination is (25.5 +- 8.0) x 10^-10, i.e., 3.2 standard deviations.
