Title: 氘核从混合模型模拟中的椭圆流

Abstract: Elliptic flow of deuterons is measured on simulated collisions events of Pb+Pb at CMS energy of 2.76 TeV per colliding nucleon pair. We use hybrid model that includes hydrodynamics for the deconfined phase and hadron transport as an afterburner. For deuterons, two production mechanisms are examined: coalescence, and direct thermal production during hadronisation and subsequent transport through the hadronic phase. Differential elliptic flow of deuterons in different centrality bins is evaluated for both implemented production models. In this approach, coalescence describes the experimental data better than direct deuteron production. Show Chinese abstract

Abstract: 重子的椭圆流在每对碰撞核子2.76 TeV的CMS能量下，通过对Pb+Pb模拟碰撞事件进行测量。我们使用包含禁闭相的流体力学和强子传输作为后续加速器的混合模型。对于重子，研究了两种生成机制：凝聚和在强子化过程中直接热生成，以及随后通过强子相的传输。评估了不同中心度区间的重子的微分椭圆流，针对两种实现的生成模型。在这种方法中，凝聚比直接重子生成更好地描述了实验数据。
