We review lattice studies of the color screening in the quark-gluon plasma. We put the phenomena related to the color screening into the context of similar aspects of other physical systems (electromagnetic plasma or cold nuclear matter). We discuss the onset of the color screening and its signature and significance in the QCD transition region, and elucidate at which temperature and to which extent the weak-coupling picture based on hard thermal loop expansion, potential nonrelativistic QCD, or dimensionally-reduced QCD quantitatively captures the key properties of the color screening. We discuss the different regimes pertaining to the color screening and thermal dissociation of the static quarks in depth for various spatial correlation functions that are studied on the lattice, and clarify the status of their asymptotic screening masses. We finally discuss the screening correlation functions of dynamical mesons with a wide range of flavor and spin content, and how they conform with expectations for low- and high-temperature behavior.

量子色动力学中的颜色筛选

我们回顾了夸克-胶子等离子体中颜色筛选的晶格研究。我们将与颜色筛选相关的现象置于其他物理系统(电磁等离子体或冷核物质)的类似方面的背景中。我们讨论了颜色筛选的开始及其在 QCD 过渡区域中的特征和意义,并定量阐明了基于硬热环膨胀、潜在非相对论 QCD 或降维 QCD 的弱耦合图像在哪个温度下以及在多大程度上捕获颜色筛选的关键属性。我们讨论了与在晶格上研究的各种空间相关函数的静态夸克的颜色筛选和热解离有关的不同机制,并阐明了它们的渐近筛选质量的状态。
