标题： Universal Features of Chiral Symmetry Breaking in Large-$N$ QCD

摘要： 我们通过将非微扰确定的低能狄拉克谱与手征随机矩阵理论（RMT）预测进行比较，研究大-$N$ QCD 中手征对称性破缺的普遍特性。 我们的数值蒙特卡罗计算基于狄拉克算子的手征格点离散化，并利用扭曲体积缩减达到$N$高达841。 将格点数据与RMT解析结果匹配，我们能够提取大-$N$的手征凝聚态，这与最近通过扭曲体积缩减模型使用非手征威尔逊夸克得到的确定结果进行了比较。 显示英文摘要

摘要： We investigate the universal features of chiral symmetry breaking in large-$N$ QCD by comparing non-perturbative determinations of the low-lying Dirac spectrum with chiral Random Matrix Theory (RMT) predictions. Our numerical Monte Carlo calculations are based on a chiral lattice discretization of the Dirac operator, and exploit twisted volume reduction to reach $N$ as large as 841. Matching lattice data with RMT analytic results, we are able to extract the large-$N$ chiral condensate, which is compared with a recent determination obtained with non-chiral Wilson quarks from twisted volume-reduced models.
