PRECISION MEASUREMENT OF MUON G-2 AND ACCELERATOR RELATED ISSUES

Creators

Description

A precision measurement of the anomalous g value, aμ=(g-2)/2, for the positive muon has been made using high intensity protons available at the Brookhaven AGS. The result based on the 1999 data aμ=11659202(14)(6) x 1010 (1.3ppm) is in good agreement with previous measurements and has an error one third that of the combined previous data. The current theoretical value from the standard model is aμ (SM)=11659159.6(6.7) x 1010 (0.57 ppm) and differ by over 2.5 standard deviation with experiment. Issues with reducing systematic errors and enhancing the injection and storage efficiencies are discussed
