AI 中文摘要
我们提出了一种在展开动力学框架内表述量子场论的方法，该框架最初发展于高自旋规范理论。我们构建了一个展开系统，用以描述标量量子场论顶点函数的Schwinger-Dyson方程层级，以展开的一阶方程形式呈现。所构建系统的一个显著特征是出现了两个额外的演化参数，分别负责WKB和RG行为。作为示例，我们对具有四次自相互作用的理论进行了单圈分析。
英文摘要
We propose a formulation of a quantum field theory within the framework of the unfolded dynamics approach, originally developed in higher-spin gauge theory. We construct an unfolded system that describes a hierarchy of Schwinger-Dyson equations for vertex functions of a scalar QFT in terms of unfolded first-order equations. A distinctive feature of the constructed system is the appearance of two additional evolution parameters responsible for the WKB and RG behaviors. As an illustration, a one-loop analysis of the theory with quartic self-interaction is carried out.
