Electroweak corrections to the muon anomalous magnetic moment

Abstract

The two-loop electroweak radiative corrections to the muon's anomalous magnetic moment, $a_μ\equiv (g_μ-2)/2$, are presented. We obtain an overall 22.6\% reduction in the electroweak contribution $a_μ^{\rm EW}$ from $195\times 10^{-11}$ to $151(4)\times 10^{-11}$. 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.
