摘要

产生粒子的方位各向异性是对相对论重离子碰撞中产生的强相互作用物质输运性质敏感的重要观测值之一。在这项工作中，我们报告了在sNN=4.5−200 Gev下，用粘性hydro+cascade混合模型vHLLE+UrQMD计算出的Au+Au碰撞中已识别的带电强子的椭圆流(v2)，并与已发表的STAR和PHENIX实验结果进行了直接比较。研究结果对未来NICA对撞机的束流能量扫描实验有一定的预测价值。

Evolution of elliptic flow of produced particles from Au+Au collisions at sNN=4.5−200 Gev in a hybrid model

Azimuthal anisotropy of produced particles is one of the important observables sensitive to the transport properties of the strongly interacting matter created in relativistic heavy-ion collisions. In this work, we report on the calculations of elliptic flow (v2) of identified charged hadrons produced in Au+Au collisions at sNN=4.5−200 Gev from a viscous hydro+cascade hybrid model vHLLE+UrQMD and provide the direct comparison with published results from STAR and PHENIX experiments. The results would be useful as predictions for the upcoming beam energy scan experiments at NICA Collider.
