赝标量极的贡献是 μ 子 g− 2 中 O (α 3) 强子逐光散射效应的主要来源。我们已经研究了这一贡献，考虑到从现有实验数据推导出的赝标量-光子-光子异常顶点的离壳结构。我们的工作改进了对μ子 g− 2 的强子逐光散射贡献的估计− 79.2 (15.4)× 10− 11 。
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 pseudoscalar-photon-photon anomaly vertex deduced from available experimental data. Our work leads to an improved estimate− 79.2 (15.4)× 10− 11 for the total hadronic light-by-light scattering contribution to the muon g− 2.
