The anomalous magnetic moment of the negative muon has been measured to a precision of 0.7 ppm (ppm) at the Brookhaven Alternating Gradient Synchrotron. This result is based on data collected in 2001, and is over an order of magnitude more precise than the previous measurement for the negative muon. The result a(mu(-))=11 659 214(8)(3) x 10(-10) (0.7 ppm), where the first uncertainty is statistical and the second is systematic, is consistent with previous measurements of the anomaly for the…

THE BROOKHAVEN MUON ANOMALOUS MAGNETIC MOMENT EXPERIMENT

▪ Abstract The E821 Experiment at the Brookhaven Alternating Gradient Synchrotron has measured the muon anomalous magnetic moment aμ to a relative precision of 0.5 parts per million. This effort

Anomalous magnetic moment of the muon

The anomalous magnetic moment of the muon, aμ, is a unique quantity that allows high-precision tests of the Standard Model. Currently, a difference of 3 to 4 standard deviations is observed between

Measurement of the electric dipole moment and magnetic moment anomaly of the muon

The experimental precision of the anomalous magnetic moment of the muon has been improved to 0.5 part-per-million by the Brookhaven E821 experiment, similar to the theoretical uncertainty. In the

The history of the muon (g-2) experiments

I discuss the history of the muon (g-2)(g−2) measurements, beginning with the Columbia-Nevis measurement that observed parity violation in muon decay, and also measured the muon gg-factor for the
