摘要：
我们利用能够捕捉夸克退禁闭相变、液气相变和临界点等特征的手征平均场（CMF）模型，探索量子色动力学（QCD）相图的复杂性。我们在CMF框架内引入矢量介子重正化，从而能够精确调整与矢量介子相互作用相关的介子质量和耦合强度。通过对退禁闭势进行新的拟合，我们能够复现近期格点QCD结果、低能核物理性质、中子星观测数据以及符合现代约束的关键相图特征。该方法增进了我们对矢量介子在核相互作用中介导作用及其对状态方程影响的理解，有助于更全面地认识QCD相图及其对核物理和天体物理现象的意义。
英文摘要：
We explore the Quantum Chromodynamics (QCD) phase diagram's complexities, including quark deconfinement transitions, liquid-gas phase changes, and critical points, using the chiral mean-field (CMF) model that is able to capture all these features. We introduce a vector meson renormalization within the CMF framework, enabling precise adjustments of meson masses and coupling strengths related to vector meson interactions. Performing a new fit to the deconfinement potential, we are able to replicate recent lattice QCD results, low energy nuclear physics properties, neutron star observational data, and key phase diagram features as per modern constraints. This approach enhances our understanding of vector mesons' roles in mediating nuclear interactions and their impact on the equation of state, contributing to a more comprehensive understanding of the QCD phase diagram and its implications for nuclear and astrophysical phenomena.
