Title: SU(6) 模型重新审视

Abstract: We discuss the vacuum structure of the SU(6) model, a chiral gauge theory, from the perspective of anomaly matching. To this end, we first identify all possible 't Hooft anomalies in the UV theory using the Stora-Zumino procedure. Subsequently, we construct an effective theory by applying the idea of the Wess-Zumino-Witten action to derive the topological terms that encode the 't Hooft anomalies. As a result, we demonstrate that a low-energy effective theory reproducing one of the anomalies, namely the mixed anomaly, is described by a Z3-valued scalar field. On the other hand, the effective theory that accounts for the discrete chiral self-anomaly is significantly more intricate, and elucidating its structure remains an ongoing challenge.

Abstract: 我们从反常匹配的角度讨论SU(6)模型的真空结构，这是一个手征规范理论。 为此，我们首先使用Stora-Zumino方法识别紫外理论中所有可能的't Hooft反常。 随后，我们通过应用Wess-Zumino-Witten作用量的思想来推导编码't Hooft反常的拓扑项，从而构建一个有效理论。 结果表明，能够再现其中一种反常（即混合反常）的低能有效理论由一个Z3值标量场描述。 另一方面，解释离散手征自反常的有效理论要复杂得多，其结构的阐明仍然是一个持续的挑战。
