标题： Nonperturbative potential for study of quarkonia in QGP

摘要： 可以定义一个热势能，以帮助理解夸克胶子等离子体中类夸克态的行为。 从格点QCD非微扰地评估这个势能是困难的，因为它涉及实时关联函数，并且经常使用贝叶斯分析，这带来了相关的系统误差。 在这项工作中，我们表明利用静态类夸克态的热关联函数的性质，可以直接从欧几里得威尔逊环数据中提取类夸克态的热势能。 这导致了一种受控的提取方法，并使我们能够判断各种模型势能的适用性。 我们还讨论了类夸克态在胶子等离子体中的现象学。 显示英文摘要

摘要： A thermal potential can be defined to facilitate understanding the behavior of quarkonia in quark-gluon plasma. A nonperturbative evaluation of this potential from lattice QCD is difficult, as it involves real-time corelation function, and has often involved the use of Bayesian analysis, with its associated systematics. In this work we show that using the properties of the static quarkonia thermal correlation functions, one can directly extract a thermal potential for quarkonia from Euclidean Wilson loop data. This leads to a controlled extraction, and allows us to judge the suitability of various model potentials. We also discuss the phenomenology of quarkonia in the gluonic plasma.
