论文摘要
在Fokker-Planck方法中，已经估计了在强磁化夸克 - 胶状等离子体中估计纵向散装粘性压力对重夸克动力学的影响。在存在磁场的情况下，已经获得了对体积自由度的动量分布的大量粘性修饰，同时结合了热磁化QCD培养基的现实状态。当磁场破坏介质的各向同性时，分析是沿纵向和横向进行的方向进行的。纵向大块粘性的贡献被认为在磁化培养基中的重夸克动量扩散中具有相当大的作用。在分析中，已经探索了较高的兰道水平和状态方程对重夸克运输的粘性校正。
The effects of longitudinal bulk viscous pressure on the heavy quark dynamics have been estimated in a strongly magnetized quark-gluon plasma within the Fokker-Planck approach. The bulk viscous modification to the momentum distribution of bulk degrees of freedom has been obtained in the presence of a magnetic field while incorporating the realistic equation of state of the hot magnetized QCD medium. As the magnetic field breaks the isotropy of the medium, the analysis is done along the directions longitudinal and transverse to the field. The longitudinal bulk viscous contribution is seen to have sizable effects in the heavy quark momentum diffusion in the magnetized medium. The dependence of higher Landau levels and the equation of state on the viscous correction to the heavy quark transport has been explored in the analysis.
