The Anomalous Magnetic Moment of the Muon: Status and Perspectives
Abstract
We review the status of the anomalous magnetic moment of the muon as a precision probe of physics beyond the Standard Model after the release of the final results from the Fermi National Accelerator Laboratory (FNAL) Muon g − 2 experiment and the second white paper of the Muon g − 2 Theory Initiative. While the Standard Model prediction requires further improvements by a factor of four to fully leverage the sensitivity achieved in experiment, the FNAL measurement will set the standard for many years to come, and we discuss a variety of features of the experimental campaign that made this achievement possible. In going forward, we discuss current efforts to improve the Standard Model prediction, and we imagine how an experiment would have to be devised to surpass 124 ppb in precision.
