论文摘要
基于在有限温度和零化学电位的频谱分析中，研究了地面状态$ q \ bar {q} $ Mesons的中等行为，其中vector和Axial-Vector通道中的$ q \ in \ {u，d，d，s，s，c \} $，在矢量和轴向矢量通道中。我们首先通过解决彩虹 - 阵导近似中的夸克差距方程和不均匀的伯特 - 盐方程来计算相关器。使用现象学ANSATZ，通过拟合相关器来提取光谱函数。通过分析光谱函数与温度的演变，我们获得了介子的分离温度，并讨论了它们与手性对称性恢复的临界温度的关系。结果显示了介子热解离的风味依赖性的模式。
The in-medium behavior of ground-state $q\bar{q}$ mesons, where $q \in \{u,d,s,c\}$, in vector and axial-vector channels is studied based on the spectral analysis for mesonic correlators at finite temperature and zero chemical potential. We first compute the correlators by solving the quark gap equations and the inhomogeneous Bethe-Salpeter equations in the rainbow-ladder approximation. Using a phenomenological ansatz, the spectral functions are extracted by fitting the correlators. By analyzing the evolution of the spectral functions with the temperature, we obtain the dissociation temperatures of mesons and discuss their relations to the critical temperature of the chiral symmetry restoration. The results show a pattern of the flavor dependence of the thermal dissociation of the mesons.
