Abstract
Bosonic two-loop electroweak radiative corrections to the muon's anomalous magnetic moment, , are presented. We find for GeV. Combining that result with our previous two-loop fermionic calculation, we obtain an overall 22.6% reduction in from 195 × to 151(4) × . Implications for the full standard model prediction and an upcoming high precision measurement of are briefly discussed. We also give the two-loop electroweak corrections to the anomalous magnetic moments of electron and tau lepton; they result in a reduction of the one-loop estimates by 35% and 15%, respectively.
