强子相对在LHC观测到的各向异性流有多大贡献?

How much does the hadronic phase contribute to the observed anisotropic flow at the LHC?

Raimond Snellings

摘要:

椭圆流表明在重离子碰撞中所产生的物质成分之间存在着多重相互作用。这包括来自不同阶段的可能贡献,包括强子阶段。在这些程序中,我将首先表明,椭圆流的能量依赖性,最近的ALICE和STAR光束能量扫描测量的基础上,可以在很大程度上理解的一个升压热系统。此外,识别粒子椭圆流测量的ALICE合作和粘性流体动力学模型计算与强子加力燃烧室之间的详细比较进行约束的可能影响的个人强子-强子再相互作用截面。

英文摘要:

Elliptic flow signals the presence of multiple interactions between the constituents of the created matter in heavy-ion collisions. This includes possible contributions from the different phases, including the hadronic phase. In these proceedings I will first show that the energy dependence of elliptic flow, based on recent ALICE and STAR beam energy scan measurements, can largely be understood in terms of a boosted thermal system. In addition, a detailed comparison between the identified particle elliptic flow measured by the ALICE collaboration and viscous hydrodynamical model calculations with and without a hadronic afterburner is performed to constrain the possible effects of individual hadron-hadron re-interaction cross-sections.
