Standard Model Predictions for the Muon (g − 2)/2
where e, m and g are the charge, mass and gyromagnetic factor of the particle. In the Dirac theory of a charged pointlike spin-1/2 particle, g = 2, and QED effects slightly increase the g value. Conventionally, a quantity a ≡ (g−2)/2 is referred to as the anomalous magnetic moment. The electron and muon anomalous magnetic moments have been measured with a very high relative accuracy of 0.24 ppb...

متن کاملDisagreement between Standard Model and Experiment for Muon G - 2 ?
In a recent experimental paper reporting a precise measurement of the muon anomalous magnetic moment, Brown et al. claim disagreement of their result with evaluations based on the standard model. This claim is based on comparison with a single theoretical evaluation. It is pointed out that other equally legitimate theoretical evaluations exist in the literature, with which the new experimental ...
متن کاملThe Muon Anomalous Magnetic Moment and the Standard Model
The muon anomalous magnetic moment measurement, when compared with theory, can be used to test many extensions to the standard model. The most recent measurement made by the Brookhaven E821 Collaboration reduces the uncertainty on the world average of aμ to 0.7 ppm, comparable in precision to theory. This paper describes the experiment and the current theoretical efforts to establish a correct ...
