The pseudoscalar pole contribution is the dominant source of the O(α 3 ) hadronic light-by-light scattering effect in muon g -2.We have examined this contribution taking account of the off-shell structure of the pseudoscalarphoton-photon anomaly vertex deduced from available experimental data.Our work leads to an improved estimate, -79.2 (15.4) × …
