Abstract

We review recent progress on the numerical determination of the Hadronic Light-by-Light contribution to the anomalous magnetic moment of the muon. We advocate for a slight increase of the White Paper number for its Standard Model prediction, to (102±17)×10^-11, accounting for a revised contribution from axial-vector mesons and short-distance constraints. This ∼10% larger result seems to be supported by the most recent lattice QCD evaluations.
