摘要:

本文讨论了在坐标表示中具有截断正则化的四维量子杨-米尔斯理论的重整化方面。使用背景场方法构造生成泛函,并通过准局域概率平均引入正则化。提出了两种主要类型的正则化:强变形(对涨落场进行平均)和弱变形(对背景场的规范变换是第一种情况的协变推广)。本文研究了前两个量子修正的奇异贡献,并与维数正则化的情况进行了详细比较。分析了引入正则化并进行重整化程序后作用量和运动方程的一致性。研究了新的对顶点,特别是它们的局域性性质和对正则化参数的依赖性。

英文摘要:

The paper discusses renormalization aspects of the quantum four-dimensional Yang-Mills theory with a cutoff regularization in the coordinate representation. The background field method is used to formulate a generating functional, and the regularization is introduced through quasi-local probabilistic averaging. Two main types of regularization are proposed: strong deformation, which consists in averaging fluctuation fields, and weak deformation, which is a covariant generalization of the first case with respect to gauge transformations of the background field. We study singular contributions for the first two quantum corrections in this paper and compare them in detail with the case of dimensional regularization. The consistency of the action and the equation of motion after introducing the regularization and making a renormalization procedure is analyzed. New counter-vertices are studied, in particular their locality properties and dependence on the regularization parameter.
