摘要:

我们给出了在2+1味畴壁QCD模拟中畴壁费米子剩余质量对第五维尺寸的依赖性及其与相应厄米Wilson Dirac算符的低本征向量的密度和局域化性质的关系.使用DBW 2和Iwasaki规范作用量,我们生成了具有$16^3\times 32$时空体积和在第五维中为8的海夸克的配置的系综。我们证明了存在一个制度的地方,手征对称性破缺的大小和拓扑结构的变化率的程度可以接受的逆晶格间距$a^{-1} \ge 1.6$ GeV。

英文摘要:

We present results for the dependence of the residual mass of domain wall fermions (DWF) on the size of the fifth dimension and its relation to the density and localization properties of low-lying eigenvectors of the corresponding hermitian Wilson Dirac operator relevant to simulations of 2+1 flavor domain wall QCD. Using the DBW2 and Iwasaki gauge actions, we generate ensembles of configurations with a $16^3\times 32$ space-time volume and an extent of 8 in the fifth dimension for the sea quarks. We demonstrate the existence of a regime where the degree of locality, the size of chiral symmetry breaking and the rate of topology change can be acceptable for inverse lattice spacings $a^{-1} \ge 1.6$ GeV.
