论文摘要
有效夸克潜力的假想部分与重夸克 - 易夸克结合状态的中等内衰减宽度有关。我们通过测量威尔逊回路的时间衰减，使用实时杨麦克膜动力学的经典统计模拟提取该数量的静态极限。通过对更精细和较大的晶格进行仿真，我们可以证明非扰动结果遵循与扰动相同的形式。对于大夸克式的分离，我们将非扰动远程校正的大小量化为重夸克电位的假想部分。我们介绍了各种温度，晶格间距和晶格量的结果。我们还提取了经典潜力的短途行为的近似值。
The imaginary part of the effective heavy-quark potential is related to the total in-medium decay width of heavy quark-antiquark bound states. We extract the static limit of this quantity using classical-statistical simulations of real-time Yang-Mills dynamics by measuring the temporal decay of Wilson loops. By performing the simulations on finer and larger lattices, we are able to show that the nonperturbative results follow the same form as the perturbative ones. For large quark-antiquark separations, we quantify the magnitude of the non-perturbative long-range corrections to the imaginary part of the heavy-quark potential. We present our results for a wide range of temperatures, lattice spacings, and lattice volumes. We also extract approximations for the short-distance behavior of the classical potential.
