Analyticity in a phenomenology of electro-weak structure of hadrons
摘要：
在强子的电弱结构的现象学的应用程序的解析性的效用证明了一些新的和实验验证的结果。为此，首先解决了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，并评述了由相应的费曼图确定形状因子的最低正常和反常奇异性的一般方法。然后利用强子电弱形状因子和各种电磁过程振幅的解析性质，进行了许多有用的应用。
英文摘要：
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.
