论文摘要
流量已成为对相对论重离子碰撞中产生的热培养基特性的关键探针。初始状态波动的演变在流量系数的功率谱上留下了烙印。因此，流量系数是由碰撞核的Parton分布引起的初始状态波动的关键探针。这与宇宙微波背景辐射（CMBR）各向异性的功率谱的物理学具有非常强烈的对应关系，该辐射（CMBR）各向异性直接探测初始通货膨胀波动。在开发高流量系数的测量技术方面，已经进行了许多工作来探究这些有趣的互连。我们对这些发展进行了简短的评论。初始磁场对这些特征的影响也将进行审查。鉴于即将到来的电子离子对撞机，所有这些都特别重要，这将直接探测碰撞核的初始Parton分布。
Flow has emerged as a crucial probe for the properties of the thermalized medium produced in relativistic heavy-ion collisions. The evolution of initial state fluctuations leaves imprints on the power spectrum of flow coefficients. Therefore flow coefficients are a crucial probe of initial state fluctuations arising from the parton distributions of the colliding nuclei. This has a very strong correspondence with the physics of power spectrum of cosmic microwave background radiation (CMBR) anisotropies which directly probes initial inflationary fluctuations. Much work has been done to probe these interesting interconnections, in particular, in developing techniques for the measurements of higher flow coefficients. We present a short review of these developments. The effect of initial magnetic field on these features will also be reviewed. All this acquires special importance in view of upcoming electron-ion collider which will directly probe initial parton distribution of the colliding nucleus.
