Hint of New Physics? An overview of the latest result from the Muon g–2 Experiment

Synopsis

The Muon g–2 Experiment looks for evidence of new particles and forces by making precise measurements of the dimensionless magnetic moment, g  of the muon. By comparing the experimental value with theoretical predictions, the experiment conducts a stringent test of the Standard Model. A discrepancy could be a possible indication of new physics. After an overview of the status of theory calculations for the muon g-2 and the efforts of the Muon g 2 Theory Initiative, I will discuss the first results of the new Muon g-2 Experiment at Fermilab which measured g with a precision slightly better than the Brookhaven National Laboratory.
