由Bethe-Salpeter 理论形式和一般的相对论协变量子场论出发,用一个简单的复合模型说明,实验观察到的μ介子反常磁矩对标准模型的偏离可能是轻子内部的结构效应,并且在不同的重组元和轻组元的情况下给出对轻子半径的限制.
Based on the Bethe-Salpeter formalism and the general relativistic covariant quantum field theory,we illustrate with a simple composite model that the observed deviation of (g-2)μ can be an effect of the substructure of muon and give the constraints on the radius of muon in different cases of light constituents and heavy constituents.
