重离子碰撞中集体流的束流能量依赖性

The beam energy dependence of collective flow in heavy ion collisions

Hannah Petersen, Jan Steinheimer, Jussi Auvinen, Marcus Bleicher

摘要:

重离子研究的主要目标是探索量子色动力学(QCD)的相图和研究夸克-胶子等离子体(QGP)的性质,QGP是在高温和/或高密度下产生的一种新的物质状态。集体各向异性流是了解相对论重离子反应中产生的系统性质的最有希望的观测量之一。总结了混合输运加流体动力学方法中产生的粒子$v_1$至$v_3$的方位角分布的前三个傅立叶系数的束能量依赖性的当前状态。

英文摘要:

The major goals of heavy ion research are to explore the phase diagram of quantum chromodynamics (QCD) and to investigate the properties of the quark gluon plasma (QGP), a new state of matter created at high temperatures and/or densities. Collective anisotropic flow is one of the most promising observables to gain insights about the properties of the system created in relativistic heavy ion reactions. The current status of the beam energy dependence of the first three Fourier coefficients of the azimuthal distribution of the produced particles $v_1$ to $v_3$ within hybrid transport plus hydrodynamics approaches are summarized.
