标题： Color Confinement in Lattice Landau Gauge

摘要： 在Kugo-Ojima准则和Gribov-Zwanziger理论的背景下，简要回顾了格点Landau规范QCD中的颜色禁闭问题。 通过$\beta=6.4,32^4,48^4$格点模拟测量了胶子传播子、鬼传播子、Kugo-Ojima参数和运行耦合，研究了Landau规范QCD的红外性质。 数据在$\widetilde{MOM}$方案的最小敏感性(PMS)原则下进行分析。 我们观察到运行耦合$\alpha_s(q)$在约1处有一个最大值，并且在q=0附近减小。 预期为1的Kugo-Ojima参数约为0.8。 显示英文摘要

摘要： The problem of color confinement in lattice Landau gauge QCD is briefly reviewed in the light of Kugo-Ojima criterion and Gribov-Zwanziger theory. The infrared properties of the Landau gauge QCD is studied by the measurement of the gluon propagator, ghost propagator, Kugo-Ojima parameter and the running coupling via $\beta=6.4,32^4,48^4$ lattice simulation. The data are analyzed in the principle of minimum sensitivity(PMS) in the $\widetilde{MOM}$ scheme. We observe the running coupling $\alpha_s(q)$ has a maximum about 1 and decreases near q=0. The Kugo-Ojima parameter, which is expected to be 1 was about 0.8.
