THE ASYMPOTOTIC BEHAVIOR OF ELECTROMAGNETIC FORM-FACTORS OF THE NUCLEON AND CALLAN-SYMANZIK EQUATION
核子电磁形状因子的渐近行为与Callan-Symanzik方程

It is shown that for the model in which nucleons couple with pseudo-scalar mesons, the homogeneous Callan-Symanzik equation can be used to investigate the asym-pototic behavior of electromagnetic form-factors of the nucleons. In this way, the leading-logarithm terms in the perturbation theory of electromagnetic form-factors of the nucleon in this model are calculated, and some more general cases are discussed.
