论文摘要
我们回顾了有关各向异性流（$ v_1，v_2，v_3 $）在相对论重型离子碰撞中产生的各向异性流量的研究（$ v_1，v_2，v_3 $）。由于培养基的各向异性压力梯度，开发了大量培养基的集体流动。魅力夸克（Charm Quarks）与散装媒介（Charm Quarks）强烈结合，从扩展的培养基中携带集体流，这将通过合并过程被再生炭遗传而来。在事件碰撞中，核子位置从平滑分布中波动，中等初始能量密度存在三角形。由于最初的波动，可以开发大量培养基的三角流量和重型风味颗粒。在纵向方向上，初始能量密度的速度-ODD分布是通过非中央重型离子碰撞中培养基的旋转引起的。 Charmonium沿正向（向后）速度的正面和负$ x $导向沿偏置解离。炭的定向流量变为非零。 charmonium的定向，椭圆和三角流（$ v_1，v_2，v_3 $）来自横向和纵向方向的中等能量密度的各向异性初始分布。
We review recent studies about anisotropic flows ($v_1, v_2, v_3$) of charmonium in the quark-gluon plasma produced in relativistic heavy-ion collisions. Collective flows of the bulk medium are developed due to the anisotropic pressure gradient of the medium. Strongly coupled with the bulk medium, charm quarks carry collective flows from the expanding medium, which will be inherited by the regenerated charmonium via the coalescence process. In event-by-event collisions where nucleon positions fluctuate from the smooth distribution, there is triangularity in the medium initial energy density. Triangular flows of the bulk medium and heavy flavor particles can be developed due to the initial fluctuations. In the longitudinal direction, the rapidity-odd distribution of the initial energy density is induced by the rotation of the medium in non-central heavy-ion collisions. Charmonium suffers biased dissociation along positive and negative $x$-directions in forward (backward) rapidity. The directed flow of charmonium becomes non-zero. The directed, elliptic and triangular flows ($v_1, v_2, v_3$) of charmonium come from the anisotropic initial distributions of the medium energy density in the transverse and longitudinal directions.
