Precise Measurement of the Positive Muon Anomalous Magnetic Moment
Abstract
A precise measurement of the anomalous g value, aμ = \(g-2\)/2, for the positive muon has been made at the Brookhaven Alternating Gradient Synchrotron. The result aμ+ = 11 659 202\(14\) \(6\)×10-10 (1.3 ppm) 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\(SM\) = 11 659 159.6\(6.7\)×10-10 (0.57 ppm) and aμ\(exp\)-aμ\(SM\) = 43\(16\)×10-10 in which aμ\(exp\) is the world average experimental value.
