味道分裂交错作用：特征值，手征性和Symanzik改进
Taste-split staggered actions: eigenvalues, chiralities and Symanzik improvement
摘要：
研究了具有Adams和Hoelbling质量项的交错费米子的本征谱。本征模的手征性反映了是否考虑了与非风味近似（γ_5 \times 1）或风味精确（γ_5 \times 1 - 5）交错对称相关联的手征性，以及使用RR、LR、RL、LL本征模定义中的哪一个。在这两种情况下的拓扑电荷的规范background. We讨论了如何删除这些行动的适当调整的改进项和/或重叠程序的装置的领先截止效应的灵敏度。Symanzik改进和链接涂抹的结合从根本上改善了物理分支的性质。
英文摘要：
The eigenvalue spectra of staggered fermions with an Adams and/or Hoelbling mass term are studied. The chiralities of the eigenmodes reflect whether the chirality linked to the unflavored approximate (γ_5 \times 1) or the flavored exact (γ_5 \times ξ_5) staggered symmetry is considered, and which one of the RR, LR, RL, LL eigenmode definitions is used. In either case a sensitivity to the topological charge of the gauge background is found. We discuss how to remove the leading cut-off effects of these actions by means of a properly tuned improvement term and/or the overlap procedure. The combination of Symanzik improvement and link smearing radically improves the properties of the physical branch.
