论文摘要
我们研究了重离子碰撞中的伪依赖性水动力反应。获得椭圆流的差异流体关系。使用3+1D音乐的事件模拟，并通过多相传输（AMPT）模型生成初始条件，验证了差异响应关系。基于响应关系，我们发现伪质性中椭圆流的两点相关性分离为流体反应和初始偏心率的两点相关性。
We study the pseudorapidity dependent hydrodynamic response in heavy-ion collisions. A differential hydrodynamic relation is obtained for elliptic flow. Using event-by-event simulations of 3+1D MUSIC, with initial conditions generated via a multi-phase transport (AMPT) model, the differential response relation is verified. Based on the response relation, we find that the two-point correlation of elliptic flow in pseudorapidity are separated into the fluid response and the two-point correlation of initial eccentricity.
