具有非线性对称实现的有效模型中的反常现象

On anomalies in effective models with nonlinear symmetry realization

Andrej Arbuzov, Boris Latosh

摘要:

讨论了具有非线性对称实现的模型的反常特征。结果表明,这样的模型可以有异常振幅打破其原来的对称性实现。一个简单的模型与非线性共形对称实现的说明性例子。通过非线性对称性实现得到的有效作用量可以用来获得驱动低能动力学的反常诱导作用量。

英文摘要:

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.
