标题： A new approach to perturbative theory in the nonperturbative QCD vacuum

摘要： 使用随机量化方法，我们推导出规范不变方程，连接非微扰场配置在量子背景中的多点真空关联函数。提出了这组方程的三种替代随机正则化方法，并在微扰理论的最低阶得到了背景场的正则化传播子。 显示英文摘要

摘要： Using stochastic quantization method we derive gauge-invariant equations, connecting multilocal vacuum correlators of nonperturbative field configurations immersed into the quantum background. Three alternative methods of stochastic regularization of these equations are suggested, and the corresponding regularized propagators of a background field are obtained in the lowest order of perturbation theory.
