论文摘要
我们使用多级算法和三个不同的小晶格间距来计算SU（2）晶格仪理论中的杂种静态电位。所得的静态电势对夸克 - 易夸克的分离有效至0.05 fm，这是重要的，例如当计算出生型近似值中的重杂交介子的质量时。我们还讨论并排除了拓扑冻结，有限的晶格量和粘合球衰减中可能的系统错误。
We compute hybrid static potentials in SU(2) lattice gauge theory using a multilevel algorithm and three different small lattice spacings. The resulting static potentials, which are valid for quark-antiquark separations as small as 0.05 fm, are important e.g. when computing masses of heavy hybrid mesons in the Born-Oppenheimer approximation. We also discuss and exclude possible systematic errors from topological freezing, the finite lattice volume and glueball decays.
