Abstract

Bosonic two-loop electroweak radiative corrections to the muon's anomalous magnetic moment, ${a}_{\ensuremath{\mu}}\ensuremath{\equiv}\frac{({g}_{\ensuremath{\mu}}\ensuremath{-}2)}{2}$, are presented. We find $\frac{\ensuremath{\Delta}{a}_{\ensuremath{\mu}}^{\mathrm{EW}}(2 \mathrm{loop}\mathrm{bosonic})}{{a}_{\ensuremath{\mu}}^{\mathrm{EW}}(1 \mathrm{loop})}\ensuremath{\approx}(\frac{\ensuremath{\alpha}}{\ensuremath{\pi}})\ifmmode\times\else\texttimes\fi{}[\ensuremath{-}3.6\mathrm{ln}(\frac{{M}_{W}^{2}}{{m}_{\ensuremath{\mu}}^{2}})+0.10]\ensuremath{\approx}\ensuremath{-}0.11$ for ${M}_{\mathrm{Higgs}}\ensuremath{\approx}250$ GeV. Combining that result with our previous two-loop fermionic calculation, we obtain an overall 22.6% reduction in ${a}_{\ensuremath{\mu}}^{\mathrm{EW}}$ from 195 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}11}$ to 151(4) \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}11}$. Implications for the full standard model prediction and an upcoming high precision measurement of ${a}_{\ensuremath{\mu}}$ 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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
