标题： The influence of Gribov copies on the gluon and ghost propagator

摘要： 胶子和鬼粒子传播子在纯SU(3)规范理论中对朗道规范下Gribov副本选择的依赖性被研究。 在$\beta$=5.8, 6.0和6.2处对多个格点尺寸进行了模拟。 在红外区域，鬼粒子传播子显示出对选择的依赖性，而对胶子传播子的影响无法分辨。 此外，Faddeev-Popov算子的本征值分布对Gribov副本是敏感的。 显示英文摘要

摘要： The dependence of the gluon and ghost propagator in pure SU(3) gauge theory on the choice of Gribov copies in Landau gauge is studied. Simulations were performed on several lattice sizes at $\beta$=5.8, 6.0 and 6.2. In the infrared region the ghost propagator turns out to depend on the choice, while the impact on the gluon propagator is not resolvable. Also the eigenvalue distribution of the Faddeev-Popov operator is sensitive to Gribov copies.
