论文摘要
在论文中，我们使用背景字段形式主义研究了Yang-Mills在四维时空中的有效行动。我们给出了明确的截止正规化程序的方式，然后进行两循环的重新归一化，并计算第二个$β$功能系数。我们还表明，两循环的奇异性仅在一级中包含对数部分。同时，获得了绿色功能常规零件的其他属性。
In the paper we study the Yang-Mills effective action in the four-dimensional space-time by using background field formalism. We give an explicit way of cutoff regularization procedure, then do a two-loop renormalization and calculate a second $β$-function coefficient. We also show that the two-loop singularity contains only logarithmic part in the first degree. At the same time additional properties of a Green function regular part are obtained.
