摘要

分析性在强子电弱结构的现象学中的应用，得到了一些新的实验验证的结果。为此，首先一般地解决了VMD模型的渐近行为与重子和原子核的形状因子的渐近行为不一致的问题，并评述了从相应的费曼图中确定形状因子的最低正常奇点和异常奇点的一般方法。然后利用强子的各种电磁过程的电弱形状因子和振幅的解析性质进行了许多有用的应用。

Analyticity in a phenomenology of electro-weak structure of hadrons

The utility of an application of the analyticity in a phenomenology of electro-weak structure of hadrons is demonstrated in a number of obtained new and experimentally verifiable results. With this aim first the problem of an inconsistency of the asymptotic behavior of VMD model with the asymptotic behavior of form factors of baryons and nuclei is solved generally and a general approach for determination of the lowest normal and anomalous singularities of form factors from the corresponding Feynman diagrams is reviewed. Then many useful applications by making use of the analytic properties of electro-weak form factors and amplitudes of various electromagnetic processes of hadrons are carried out.
