标题： Testing the fixed-point QCD action and the construction of chiral currents

摘要： 我们介绍了首次使用最近参数化的固定点狄拉克算子D^FP的淬火QCD测量结果。 我们还给出了手征格点作用量的协变密度和守恒电流的一般且实用的构造方法。 测量包括（a）强子谱学，（b）小手征偏差的修正，（c）通过有限尺寸标度和独立的谱学得到的重整化夸克凝聚能，（d）拓扑易感性，（e）小本征值分布和随机矩阵理论，以及（f）近零模的局部手征性和瞬子主导性。 显示英文摘要

摘要： We present the first set of quenched QCD measurements using the recently parametrized fixed-point Dirac operator D^FP. We also give a general and practical construction of covariant densities and conserved currents for chiral lattice actions. The measurements include (a) hadron spectroscopy, (b) corrections of small chiral deviations, (c) the renormalized quark condensate from finite-size scaling and, independently, spectroscopy, (d) the topological susceptibility, (e) small eigenvalue distributions and random matrix theory, and (f) local chirality of near-zero modes and instanton-dominance.
