论文摘要
我们回顾了夸克 - 格鲁隆等离子体颜色筛选的晶格研究。我们将与颜色筛选有关的现象置于其他物理系统（电磁等离子体或冷核物质）相似方面的背景下。我们讨论了颜色筛选及其在QCD过渡区域中的特征和显着性的发作，并根据硬热环扩展，潜在的非固定QCD或尺寸降低的QCD定量地捕获着颜色筛选的关键特性，并在哪个温度以及在哪个程度上进行弱耦合图。我们讨论了与静态夸克的色彩筛选和热解离的不同状态，以了解在晶格上研究的各种空间相关函数，并阐明其渐近筛选质量的状态。我们最终讨论了具有广泛风味和自旋含量的动力介体的筛选相关功能，以及它们如何符合对低温和高温行为的期望。
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.
