论文摘要
我们研究手性分离效应（CSE）和手性异常之间的关系，并认为CSE不会继承手性异常的不变性。对于电荷领先顺序的QED，并在实时形式主义中进行分类正规化，我们以正则化依赖性方式进行纠正，而该CSE是一种红外（IR）效应，而异常是超紫罗兰（UV）现象。因此，通常，CSE对改变理论特性的非扰动相互作用敏感，而异常是由Lorentz对称性固定的。这种相互作用的最简单示例是Yukawa类似的费米昂质量。
We study relation between Chiral Separation Effect (CSE) and Chiral Anomaly, and argue that CSE does not inherit the immutability of Chiral Anomaly. For QED in the leading order in electric charge, with point-splitting regularization in real-time formalism, we demontrate, in regularization-dependent way though, that CSE is an infrared (IR) effect, while the Anomaly is an ultra-violet (UV) phenomena. Thus, CSE in general is sensitive to non-perturbative interactions that alter the theory IR properties, while the Anomaly is fixed by Lorentz symmetry. The simplest example of such an interaction is the Yukawa-like fermion mass.
