论文摘要
在本文中，我们研究了Euler-Heisenberg作用的CP侵略项。我们关注与有效的动作方法中类似QED的模型中产生这样的术语相关的方面。特别是，我们表明，CP侵略项的产生与载体和轴向效率双线性密切相关。尽管这些异常模型不是QED的“可行”扩展，但我们认为，光子扇区中的CP侵略项仅从此类模型中获得，而不是从任何基本田间理论中获得的。
In this paper, we examine the CP-violating term of the Euler-Heisenberg action. We focus in the aspects related with the generation of such a term from a QED-like model in terms of the effective action approach. In particular, we show that the generation of the CP-violating term is closely related with both of vector and axial fermionic bilinears. Although, these anomalous models are not a "viable" extension of QED, we argue that the CP-violating term in the photon sector is obtained only from this class of models, and not from any fundamental field theory.
