标题： Determination of the Static Potential with Dynamical Fermions

摘要： 我们详细介绍了从动态构型上测得的威尔逊圈提取静止单胶子和反胶子对之间势能的一种方法。 这种方法基于HYP打拿，并导致威尔逊圈的信噪比呈指数级改善。 我们解释了为何能得到正确的连续极限势，并展示了数值证据表明离散效应很小。 我们给出了非微扰势的精确结果。 作为应用，我们确定了尺度r_0/a并研究了在r_0附近距离范围内的静止单胶子势的形状，从而可以将其与唯象势模型进行比较。 显示英文摘要

摘要： We present in detail a technique to extract the potential between a static quark and anti-quark pair from Wilson loops measured on dynamical configurations. This technique is based on HYP smearing and leads to an exponential improvement of the noise-to-signal ratio of Wilson loops. We explain why the correct continuum potential is obtained and show numerical evidence that the cut-off effects are small. We present precise results for the non-perturbative potential. As applications, we determine the scale r_0/a and study the shape of the static potential in the range of distances around r_0, where it can be compared with phenomenological potential models.
