Theory of Muon g-2

Abstract

The longstanding discrepancy between the measured and the predicted values of the anomalous magnetic moment of the muon, a µ = ( g − 2) / 2, is one of the most intriguing potential hints of new physics in particle physics. After a brief introduction, the status of the theoretical prediction of g-2 is presented, with some focus on the contributions yielding the dominant uncertainties. The status of the comparison with the experimental measurement is then discussed
