摘要:

在本文中,我们证明与具有连续非阿贝尔$G$-味对称性的量子场论(QFT)相关的对称拓扑场论(SymTFT)是具有规范群$G$的$BF$-理论。我们表明,用平坦联络规范$G$-对称性会得到一个具有全局对称性的理论,该对称性由$BF$-理论量子化中共轭变量的交换来表征。我们构造了生成规范QFT的$G$-味对称性和$(d-2)$-形式$\text{Rep}(G)$-对称性的扩展算符。我们证明在AdS/CFT框架中,$BF$-理论作为描述QFT的$G$-味对称性的理论出现。$G$-味对称性的't Hooft反常被实现为作用量中的额外项。

英文摘要:

In this Letter, we demonstrate that the Symmetry Topological Field Theory (SymTFT) associated to a Quantum Field Theory (QFT) with continuous non-abelian $G$-flavor symmetry is a $BF$-theory with gauge group $G$. We show that gauging $G$-symmetry with a flat connection yields a theory with global symmetry characterized by exchanging the conjugate variables in the quantization of $BF$-theory. We construct the extended operators that generate the $G$-flavor symmetry and the $(d-2)$-form $\text{Rep}(G)$-symmetry of the gauged QFT. We demonstrate that $BF$-theory arises as the theory characterizing $G$-flavor symmetry of a QFT in the AdS/CFT setup. 't Hooft anomalies of the $G$-flavor symmetry are realized as extra terms in the action.
