Status of (gμ - 2)/2 in standard model
The current status of the muon anomalous magnetic moment is discussed. The leading order hadronic contribution is reevaluated basing on the new data on e+e- annihilation. The experimental value is about 3.3 standard deviations higher than the Standard Model prediction.
