摘要

研究了交错夸克本征谱的手性性质。提出了一种利用准零模和非零模的对称性和手性来识别准零模和非零模的新方法。在此，我们回顾了HYP改进交错夸克的传统方法，并将其扩展为一种利用手性Ward恒等式和泄漏模式来实现目标的全新方法。

Chiral Ward identities for Dirac eigenmodes with staggered fermions

We study chiral properties of eigenvalue spectrum for staggered quarks. We present a new method to identify would-be zero modes and nonzero modes using their symmetry and chiral properties. Here, we review the traditional method with HYP improved staggered quarks, and extend it to a completely new method which uses the chiral Ward identities and leakage patterns to achieve the goal.
