Abstract

The anomalous gyromagnetic factor, g-2, of the leptons played an important role in the development of particle physics and continue to serve as fundamental quantities for testing the validity of the Standard Model and putting stringent constraints on theories beyond the Standard Model. Compared to the electron, the anomalous g-value of muons is in general 40000 times more sensitive to the hadronic and electro-weak effects and the effects from possible new physics because of the large mass of the muon. The talk will be about the measurement of muon g-2 to the accuracy of 0.7 parts per million in Brookhave National Lab and the theoretical predictions from the Standard Model and speculations from new physics beyond the Standard Model.
