相对论重离子碰撞中间歇的研究进展

Overview of Recent Intermittency Analysis in Relativistic Heavy-ion Collisions

  • 摘要: 探索QCD物质相结构和寻找QCD临界点是高能核物理研究的热点之一。三维Ising-QCD理论认为,临界间歇是QCD临界点的特征信号之一,而相对论重离子碰撞实验中间歇的测量是研究QCD相结构的重要实验探针。本工作简要介绍近年来相对论重离子碰撞中间歇的研究进展。在实验方面,主要介绍RHIC-STAR实验中金+金的带电强子的间歇测量结果,以及SPS-NA61/SHINE实验中氩+钪的质子的结果;在模型方面,简要介绍混合UrQMD+CMC模型的结果。最后展望了关于间歇的下一阶段研究。

     

    Abstract: One of the frontier research in high-energy nuclear physics is to study the Quantum Chromodynamics (QCD) phase diagram and locate the critical point. According to 3D Ising-QCD theory, critical intermittency is a distinctive feature of the QCD critical point, and thereby the measurement of intermittency can be served as a crucial probe for studying the QCD phase structure. This paper briefly review recent progress of intermittency analysis in relativistic heavy-ion collisions. In experiment, we present the results of charged hadrons in Au+Au collisions from the RHIC-STAR experiment, and proton results in Ar+Sc collisions from the SPS-NA61 experiment. Additionally, the results from the hybird UrQMD+CMC model are also introduced. Finally, we give a outlook for next stage of research.
