A precise measurement of the anomalous g value, a + μ = ( g − 2)/2, for the positive muon has been made at the Brookhaven Alternating Gradient Synchrotron. The result a + μ = 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 a μ(SM)= 11 659 159.6(6.7) × 10 −10 (0.57 ppm) and a μ(exp)− a μ(SM) = 42(16) × 10 −10 in which a μ(exp) is the world average experimental value.
