The anomalous magnetic moment of positive and negative muons

The anomalous g-factor a identical to (g-2)/2 has been measured for muons of both charges in the Muon Storage Ring at CERN. The two results, a/sub mu +/=1165910(12)*10/sup -9/ and a/sub mu -/=1165936 (12)*10/sup -9/, are in good agreement with each other, and combine to give a mean a/sub mu /=116592...

description The anomalous g-factor a identical to (g-2)/2 has been measured for muons of both charges in the Muon Storage Ring at CERN. The two results, a/sub mu +/=1165910(12)*10/sup -9/ and a/sub mu -/=1165936 (12)*10/sup -9/, are in good agreement with each other, and combine to give a mean a/sub mu /=1165922(9)*10/sup -9/, which is very close to the most recent theoretical prediction 1165921(10)*10/sup -9/. For the experimental results, the total statistical and systematic error is given. The measurements thus confirm the remarkable QED calculation plus hadronic contribution, and serve as a precise verification of the CPT theorem for muons.
