论文摘要
我们回顾了有关光夸克状态在QCD相图中的作用的最新结果。特别是，我们将讨论如何合并的理论技术，例如有效的理论，单位化和病房身份，有助于阐明有关手性对称性恢复的几个重要问题，并通过最近的晶格分析来建造桥梁。将要特别注意手性的角色和$ u（1）_a $伙伴在这些对称性之间的相互作用中，这对于正确理解过渡模式至关重要。在有限温度下的轻标量介子将显示出编码手性的敏感性和$ u（1）_a $恢复属性的描述。
We review recent results on the role of light quark states within the QCD phase diagram. In particular, we will discuss how the combined use of theoretical techniques such as Effective Theories, Unitarization and Ward Identities helps to shed light on several important issues regarding chiral symmetry restoration, building bridges with recent lattice analyses. Special attention will be paid to the role of chiral and $U(1)_A$ partners in the interplay between those symmetries, which is crucial to properly understand the transition pattern. Light scalar mesons at finite temperature will be shown to be responsible for the description of susceptibilities encoding chiral and $U(1)_A$ restoration properties.
