摘要：

The pseudoscalar pole contribution is the dominant source of the O(alpha(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 pseudoscalar-photon-photon anomaly vertex deduced from available experimental data. Our work leads to an improved estimate -79.2 (15.4) X 10(-11) for the total hadronic light-by-light scattering contribution to the muon g-2. [S0556-2821(98)06601-6].
