我们得到了介子的异常磁矩的光对光散射校正的介子极贡献的解析结果,a(mu) = (g(mu)-2)/2。利用介子优势向量模型求解介子跃迁形式因子,得到(LBL,pi0)mu = +56x10(-11)。
We derive an analytic result for the pion pole contribution to the light-by-light scattering correction to the anomalous magnetic moment of the muon, a(mu) = (g(mu)-2)/2. Using the vector meson dominance model for the pion transition form factor, we obtain a(LBL,pi0)mu = +56x10(-11).
