摘要:

我们表明,n循环顺序的发散内容的费曼振幅是由一组基本的(发散)积分,不需要进行评估。确定重整化群函数只需要基本发散积分的系数。导出了不同回路阶数的这些系数之间的关系。

英文摘要:

We show that to n loop order the divergent content of a Feynman amplitude is spanned by a set of basic (logarithmically divergent) integrals which need not be evaluated. Only the coefficients of the basic divergent integrals are necessary to determine renormalization group functions. Relations between these coefficients of different loop orders are derived.
