标题： Determination of the spin-dependent potentials with the multi-level algorithm

摘要： 自旋相关的修正对于描述重夸克偶素谱的精细和超精细分裂是重要的。 我们在SU(3)格点规范理论中研究这些修正，使用Polyakov环相关函数作为夸克源，并应用多级算法。 我们观察到在中等距离范围内的自旋相关势具有明显清晰的信号。 显示英文摘要

摘要： The spin-dependent corrections to the static interquark potential are relevant to describing the fine and hyper-fine splittings of the heavy quarkonium spectra. We investigate these corrections in SU(3) lattice gauge theory with the Polyakov loop correlation function as the quark source by applying the multi-level algorithm. We observe remarkably clean signals for the spin-dependent potentials up to intermediate distances.
