库仑规范Yang-Mills理论中的双时两点关联函数

Equal-time two-point correlation functions in Coulomb gauge Yang-Mills theory

D. Campagnari, A. Weber, H. Reinhardt, F. Astorga, W. Schleifenbaum

摘要:

本文用泛函微扰方法计算了库仑规范Yang-Mills理论中单圈阶静态色荷间的等时两点关联函数和势函数。泛函方法通过求解g ^2阶真空波泛函的薛定谔方程,并通过新的图解规则从泛函积分表示中导出等时关联函数。我们证明了结果与通常的拉格朗日泛函积分方法得到的结果一致,提取β函数,并确定了等时胶子和鬼两点函数和静态势的反常维数的假设下的乘法重整化到所有的订单。

英文摘要:

We apply a functional perturbative approach to the calculation of the equal-time two-point correlation functions and the potential between static color charges to one-loop order in Coulomb gauge Yang-Mills theory. The functional approach proceeds through a solution of the Schroedinger equation for the vacuum wave functional to order g^2 and derives the equal-time correlation functions from a functional integral representation via new diagrammatic rules. We show that the results coincide with those obtained from the usual Lagrangian functional integral approach, extract the beta function, and determine the anomalous dimensions of the equal-time gluon and ghost two-point functions and the static potential under the assumption of multiplicative renormalizability to all orders.
