论文摘要
我们研究了如何计算确切的重新归一化形式主义中的操作员产品扩展系数。在讨论了可能的策略之后,我们在$ε$ - expansions中明确考虑了一些示例,对于$ d = 4-ε$ dimensions的Wilson-fisher固定点和$ d = 6-ε$ dimensions中的Lee-yang模型。最后,我们讨论如何扩展我们的形式主义超越扰动理论。
We study how to compute the operator product expansion coefficients in the exact renormalization group formalism. After discussing possible strategies, we consider some examples explicitly, within the $ε$-expansions, for the Wilson-Fisher fixed points of the real scalar theory in $d=4-ε$ dimensions and the Lee-Yang model in $d=6-ε$ dimensions. Finally we discuss how our formalism may be extended beyond perturbation theory.
