论文摘要
解决了具有非线性对称性实现的模型的异常特征。结果表明,这样的模型可能会使其原始对称性实现的破坏异常。给出了一个具有非线性共形对称性实现的简单模型的说明性示例。有人认为,应使用非线性对称性实现获得的有效作用,以获得驱动低能动力学的异常诱导的作用。
Anomalous features of models with nonlinear symmetry realization are addressed. It is shown that such models can have anomalous amplitudes breaking of its original symmetry realization. An illustrative example of a simple models with a nonlinear conformal symmetry realization is given. It is argued that the effective action obtained via nonlinear symmetry realization should be used to obtain an anomaly-induced action which is to drive the low energy dynamics.
