Abstract

The two-loop electroweak radiative corrections to the muon's anomalous magnetic moment, a_μ≡ (g_μ-2)/2, are presented. We obtain an overall 22.6% reduction in the electroweak contribution a_μ^{\rm 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_μ are briefly discussed. Some aspects of the calculations are discussed in detail.
