标题： Reply to E. Shuryak's Comments on "Three regimes of QCD"

摘要： 在他最近的评论中，E. Shuryak 重申了支持在手征性恢复赝临界温度之上立即出现无禁闭夸克-胶子等离子体（QGP）的旧观点，但这些观点不幸是误导性的。 在一篇 devoted to 我们对高温下 QCD 的看法的评论中，他并未涉及甚至提及我们论点的本质。 近年来，QCD 中发现了一种新的“隐藏”对称性。 这是一种 QCD 电部分的对称性，比整个 QCD 拉格朗日量的手征对称性更高。 这种对称性在 T_c 以上空间关联函数中已被清晰观察到，并且最近也在时间关联函数中被观察到。 后者的关联函数直接与可观测的谱密度相关。 然后，以一种与模型无关的方式，我们得出结论，在 T_c 以上但大致低于 3T_c 的 QCD 中，自由度是手征对称的夸克，这些夸克通过色电场结合成无色磁效应的色单态复合物。 这一 QCD 的状态被称为弦流体，因为这些物体非常类似于弦。在更高温度下，存在一个非常平滑的过渡到部分子自由度，即进入 QGP 状态。 在这里，我们将讨论 Shuryak 提出的一些观点。 显示英文摘要

摘要： In his recent Comments E. Shuryak reiterates old, unfortunately misleading arguments in favor of deconfined Quark-Gluon Plasma (QGP) immediately above the chiral restoration pseudocritical temperature. In a Comment devoted to our view of QCD at high temperatures he does not address and even mention the essence of our arguments. In recent years a new "hidden" symmetry in QCD was discovered. It is a symmetry of the electric sector of QCD, that is higher than the chiral symmetry of the QCD Lagrangian as the whole. This symmetry was clearly observed above T_c in spatial correlators and very recently also in time correlators. The latter correlators are directly related to observable spectral density. Then in a model-independent way we conclude that degrees of freedom in QCD above T_c, but below roughly 3T_c, are chirally symmetric quarks bound by the chromoelectric field into color-singlet compounds without the chromomagnetic effects. This regime of QCD has been referred to as a Stringy Fluid since such objects are very reminiscent of strings.At higher temperatures there is a very smooth transition to the partonic degrees of freedom, i.e. to the QGP regime. Here we will address some of the points made by Shuryak.
