ERG方法中的异常
Anomalies in the ERG Approach
摘要：
在精确重整化群中采用的反场形式对描述具有某种对称性的系统，特别是规范对称性的系统是有用的。在形式主义中，量子主算符的消失意味着对称性的存在。QM算子满足一个简单的代数关系，它将被证明与Wess-Zumino异常条件有关。我们还解释了如何异常有助于QM运营商。
英文摘要：
The antifield formalism adapted in the exact renormalization group is found to be useful for describing a system with some symmetry, especially the gauge symmetry. In the formalism, the vanishing of the quantum master operator implies the presence of a symmetry. The QM operator satisfies a simple algebraic relation that will be shown to be related to the Wess-Zumino condition for anomalies. We also explain how an anomaly contributes to the QM operator.
