标题： Anomalous Action of QCD from the General Quark Propagator

摘要： 手征有效理论对$\mathcal{O}(p^4)$的异常作用通过推广在\cite{ma02}中的考虑，并包括一般夸克传播子中的波函数部分进行研究。发现 Wess-Zumino 项的 QCD 动力学依赖是显式的，这种依赖意味着为了动态生成 Wess-Zumino 项，QCD 手征对称性在低能区域必须被动态地破坏。此外，我们发现手征微扰理论动量展开中的下一阶异常作用是规范不变的并且依赖于 QCD 动力学。 显示英文摘要

摘要： The anomalous action of the chiral effective theory to $\mathcal{O}(p^4)$ is investigated by generalizing the consideration in \cite{ma02} with including the wave function part in the general quark propagator. It is found that the QCD dynamics dependence of the Wess-Zumino term is explicit and this dependence means that the QCD chiral symmetry must be broken dynamically in the low energy region for dynamically generating the Wess-Zumino term. In addition, we found that the next to leading order anomalous action in the momentum expansion of the chiral perturbation theory is gauge invariant and QCD dynamics dependent.
