UIUC Nuclear Physics Laboratory Experiments

Muon (g-2)


Experiment E821 at Brookhaven National Laboratory measures the anomalous magnetic moment of the muon with an intended precision of less than 0.5 parts per million. The present experimental  value differs from that predicted by the Standard Model of Particle Physics by 1.6 standard deviations. The previous 2.6 standard deviation difference was partly due to a mistake in the calculation, which was discovered shortly after the last experimental result was published.

The article describing the most recent experimental result was published in Physical Review Letters (H.N.  Brown e.a., Precise measurement of the positive muon anomalous magnetic moment, Phys.  Rev.  Lett.  86 (2001) 2227), which is also available from the arXiv.org e-Print archive as hep-ex/0102017.
