论文摘要
我们以光夸克和gluon的自由度来解决一个领先的QCD动力学理论,以研究夸克 - 胶体等离子体(QGP)的非平衡动力学。通过包括夸克和gluon的弹性和非弹性散射,该模型熟练地描述了QGP的动力和化学平衡,因此在早期的Partons的初始(半)硬质产生与几乎热水量化的Quark-gluon等离子体的最初(半)硬性生产相关联。在这种方法中,我们研究了QGP以零和非零的净 - 巴里昂密度的动力学和化学平衡的时间尺度和机制,并详细介绍了与喷射淬灭物理学和流体动力学的连接。
We solve a leading-order QCD kinetic theory with light quarks and gluon degrees of freedom to study the non-equilibrium dynamics of the quark-gluon plasma (QGP). By including both elastic and inelastic scatterings for quarks and gluon, the model is proficient to describe kinetic and chemical equilibration of the QGP, and thus connects the initial (semi-) hard production of partons at early times with the hydrodynamic description of a near-thermalized quark-gluon plasma after the first fm/c of the collision. Within this approach, we investigate the time scales and mechanisms for kinetic and chemical equilibration of the QGP at zero and non-zero net-baryon density and elaborate on the connections to jet quenching physics and hydrodynamics.
