论文摘要
我们已经在热培养基中调查了$ d $和$ \ bar {b} $介子的多体方程，通过应用基于手性和夸克对称性的有效野外理论。在动力学理论中利用这些对称性，我们得出了一个外壳fokker-planck方程，该方程包含了这些状态的完整频谱函数的信息。在这项贡献中，我们在魅力和底部的手性恢复温度以下的重量转运系数下方介绍了最新结果。结合温度依赖的光谱函数和相互作用的计算以及外壳效应，可以改善与手性过渡温度高于手性过渡温度的最新计算的匹配。
We have investigated the many-body equations of $D$ and $\bar{B}$ mesons in a thermal medium by applying an effective field theory based on chiral and heavy-quark symmetries. Exploiting these symmetries within kinetic theory, we have derived an off-shell Fokker-Planck equation which incorporates information of the full spectral functions of these states. In this contribution we present our latest results on heavy-flavor transport coefficients below the chiral restoration temperature, in both charm and bottom sectors. The calculation incorporating temperature-dependent spectral functions and interactions, together with off-shell effects, allows for an improved matching to the state-of-the-art calculations above the chiral transition temperature.
