We report the first predictions of elliptic flow (v2) of identified hadrons at mid-rapidity (|y|< 1.0) in Au+Au collisions at Elab=6.7,8,11,and 25 A GeV using the Parton Hadron String Dynamics (PHSD) model. The transverse momentum (pT) dependence of identified hadron v2 in different centrality intervals (0-10%, 10-40%, and 40-80%) is shown. A clear centrality dependence of v2(pT) is observed for particles at Elab=6.7,8,11,and 25 A GeV. Within the PHSD model, the number of constituent quark (NCQ) scaling of v2 approximately follows in Au+Au collisions at all beam energies. A collision energy (sNN) dependence of π, K, and pv2 is studied in comparison with available published experimental data in the beam energy range of 6-25 A GeV. These predictions will help in interpreting the data from the forthcoming Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) and Multi-Purpose Detector (MPD) at the Nuclotron-based Ion Collider facility (NICA).

使用 PHSD 模型分析重离子碰撞中已识别强子椭圆流的碰撞能量依赖性



我们报告了使用 Parton 强子串动力学 (PHSD) 模型在 Elab=6.7、8、11 和 25 A GeV 的 Au+Au 碰撞中,在中等速度 (|y|< 1.0) 下已识别强子的椭圆流 (v2) 的首次预测。显示了已识别的强子 v2 在不同中心性区间(0-10%、10-40% 和 40-80%)中的横向动量 (pT) 依赖性。对于 Elab=6.7、8、11 和 25 A GeV 的粒子,观察到 v2(pT) 的明显中心性依赖性。在 PHSD 模型中,v2 的组成夸克 (NCQ) 缩放数大约遵循所有光束能量下的 Au+Au 碰撞。在 6-25 A GeV 的光束能量范围内,与现有的已发表实验数据相比,研究了 π、 K 和 pv2 的碰撞能量 (sNN) 依赖性。这些预测将有助于解释即将在反质子和离子研究设施 (FAIR) 和基于核子的离子对撞机设施 (NICA) 进行的多用途探测器 (MPD) 的压缩重子物质 (CBM) 实验的数据。
