Constraining the neutron skin of $^{208}$ Pb with anisotropic flow in Pb+Pb collisions at the LHC

该研究利用改进的多相输运模型分析 LHC 能区 Pb+Pb 碰撞中的各向异性流，发现虽然中子皮厚度会影响初始偏心率和流系数，但 ALICE 数据排除了大厚度中子皮，且当前流测量因主要受整体碰撞几何驱动而对核表面细节缺乏极端敏感性，导致零厚度与中等厚度中子皮之间存在几何简并。

Elliptic flow of charged hadrons in d+Au collisions at $\sqrt{s_{NN}} =$ 200 GeV using a multi-phase transport model

本文利用 AMPT 模型（默认模式和弦熔化模式）对 200 GeV d+Au 碰撞中带电强子的椭圆流进行了综合分析，结果表明早期部分子相的散射截面显著影响椭圆流，而后期强子再散射影响甚微，且模型结果与 STAR 和 PHENIX 实验数据在横动量依赖性上吻合良好。
