Dynamics of the quark gluon plasma in high-energy heavy ion collisions

通过建立一个综合动力学模型，描述了高能重离子碰撞中产生的夸克胶子等离子体（QGP）的动力学，该模型统一了对应于重离子反应三个连续阶段的三个模型。该模型使我们能够逐次模拟反应，并分析实验组所做的最终粒子分布。我们还研究了QGP动力学的新现象，如马赫锥结构，并发现它对解释最近在大型强子对撞机上观察到的射流结构具有重要意义。

Dynamics of the quark gluon plasma (QGP) created in high energy heavy ion collisions is described by developing an integrated dynamical model which unifies three models corresponding to three sequential stages of heavy ion reactions. The model enables us to simulate the reactions on an event-by-event basis and to analyze final particle distribution as done by experimental group. We also investigated novel phenomenon of the QGP dynamics such as Mach cone structure and found it important to interpret the recent observation of the jet structure at Large Hadron Collider.
