Muon (g − 2): Experiment and Theory
A review of the experimental and theoretical determinations of the anomalous magnetic moment of the muon is given. The anomaly is defined by a = (g−2)/2, where the Landé g-factor is the proportionality constant that relates the spin to the magnetic moment. For the muon, as well as for the electron and tauon, the anomaly a differs slightly from zero (of order 10) because of radiative corrections...
متن کاملThe Next-generation Muon (g−2) Experiment
The muon (g − 2) experiment at the Brookhaven AGS achieved a relative precision on the muon anomalous magnetic moment, a μ , of ±0.54 ppm. The anomaly is sensitive to a wide range of physics beyond the standard model such as supersymmetry, and thus can help constrain the interpretation of any " new physics " found at the Large Hadron Collider. It is desirable to improve the precision of the exp...
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 کاملMuon Anomaly : Experiment and Theory
A summary is given of the present status of the theory and experiment of the anomalous magnetic moment of the muon. A difference between predicted and measured values is an indication of physics beyond the Standard Model. A new experimental measurement has produced a value which differs from a recent Standard Model prediction by about 1.6 standard deviations. When first announced, the discrepan...
متن کامل0 Status of the Muon ( g − 2 ) Experiment
The study of g-factors of subatomic particles can trace its roots back to the 1921 paper by Stern[2] which was a proposal to study space quantization with an apparatus which is now called a “Stern-Gerlach apparatus”. By 1924 the famous experiments had been done[3] and a review paper was written summarizing their results.[4] Their final conclusion, that “to within 10% the magnetic moment of the ...
