论文摘要
在目前的工作中，我们使用MIT袋模型的修改版本，在该版本上引入了矢量字段和自我相互作用项，以获取热夸克物质并研究QCD相图。我们首先分析了两种质量的夸克物质，这些夸克物质限制在凝结相处的冷冻液和液态气相变。后来，三种质量的夸克物质受到$β$平衡的影响，并且电荷中立性用于计算夸克恒星宏观特性，这些特性面临着最近的观察性巨大和规范的恒星半径结果。最后，进行了与从Nambu-Jona-Lasinio模型获得的QCD相图的比较。
In the present work we use the modified versions of the MIT bag model, on which both a vector field and a self-interacting term are introduced, to obtain hot quark matter and to investigate the QCD phase diagram. We first analyze two-flavored quark matter constrained to both the freeze-out and the liquid-gas phase transition at the hadronic phase. Later, three-flavored quark matter subject to $β$ equilibrium and charge neutrality is used to compute quark star macroscopic properties, which are confronted with recent observational massive and canonical star radius results. Finally, a comparison with QCD phase diagrams obtained from the Nambu-Jona-Lasinio model is performed.
