Electroweak corrections to the muon anomalous magnetic moment

Abstract

Abstract The two-loop electroweak radiative corrections to the muon's anomalous magnetic moment, a u EW  ( g u −2)/2 are presented. We obtain an overall 22.6% reduction in the electroweak contribution a μ EW from 195 × 10 −11 to 151(4) × 10 −11 . Implications for the full standard model prediction and an upcoming high precision measurement of a mu are briefly discussed. Some aspects of the calculations are discussed in detail.
