本文利用广泛采用的多相输运模型研究了相对论重离子碰撞中夸克-胶子等离子体的旋转集体运动。计算了$\ mathm {Au}+\ mathm {Au}$碰撞的全局角动量、夸克-胶子等离子体携带的平均涡量和局部定义涡量场，详细描述了它们的时间演化、空间分布以及与束流能量和碰撞中心性的依赖关系。
We study the rotational collective motion of the quark-gluon plasma in relativistic heavy-ion collisions using the widely adopted a multiphase transport (AMPT) model. The global angular momentum, the average vorticity carried by the quark-gluon plasma, and the locally defined vorticity fields are computed for $\mathrm{Au}+\mathrm{Au}$ collisions, with detailed information of their time evolution, spatial distribution, as well as the dependence on beam energy and collision centrality.
