在格点QCD中数值计算了Dirac算符的本征谱，并考虑了动力学畴壁费米子的影响.在高能量区，离散化效应变得显著。我们减去他们在领导秩序，然后采取连续极限与晶格数据在三个晶格间距。晶格结果的指数匹配连续扰动理论，这是已知的，提取强耦合常数。
The eigenvalue spectrumof the Dirac operator is numerically calculated in lattice QCD withflavors of dynamical domain-wall fermions. In the high-energy regime, the discretization effects become significant. We subtract them at the leading order and then take the continuum limit with lattice data at three lattice spacings. Lattice results for the exponentare matched to continuum perturbation theory, which is known up to, to extract the strong coupling constant.
