论文摘要
我们基于有效的量子Chromo Dynamics（QCD）的动力学理论，探索了Quark-Gluon等离子体的不平衡性动力学和有限的净 - 巴里昂密度。通过研究纵压的各向同性化，我们确定了粘性流体动力学发作的相关时间和温度尺度，并量化对QGP化学成分的依赖性。通过将我们的结果推断到现实的耦合强度，我们讨论了有关平衡阶段在不同碰撞能量中的作用的现象学后果。
We explore the out-of-equilibrium dynamics of the Quark-Gluon Plasma at zero and finite net-baryon density based on an effective kinetic theory of Quantum Chromo Dynamics (QCD). By investigating the isotropization of the longitudinal pressure, we determine the relevant time and temperature scales for the onset of viscous hydrodynamics, and quantify the dependence on the chemical composition of the QGP. By extrapolating our results to realistic coupling strength, we discuss phenomenological consequences regarding the role of the pre-equilibrium phase at different collision energies.
