论文摘要
在Fokker-Planck Dynamics的框架内研究了阻力和扩散系数，以在扩展的Quark-Gluon等离子体中传播的魅力夸克。在相对论重型离子碰撞中产生的核物质的时空演变是使用音乐建模的，是3+1 D相对论粘性水动力学方法。通过考虑在培养基中使用热夸克和胶子的散射过程来探索粘性校正对重夸克传输系数的影响。据观察，重夸克的动量扩散对剪切和散装粘度与熵比敏感。分析了粘性Quark-Gluon等离子体中魅力夸克的碰撞能量损失。
The drag and diffusion coefficients are studied within the framework of Fokker-Planck dynamics for the case of a charm quark propagating in an expanding quark-gluon plasma. The space-time evolution of the nuclear matter created in the relativistic heavy-ion collision is modelled using MUSIC, a 3+1 D relativistic viscous hydrodynamic approach. The effect of viscous corrections to the heavy quark transport coefficients is explored by considering scattering processes with thermal quarks and gluons in the medium. It is observed that the momentum diffusion of the heavy quarks is sensitive to the shear and bulk viscosity to entropy ratios. The collisional energy loss of the charm quark in the viscous quark-gluon plasma is analyzed.
