CERN LHC超相对论重离子碰撞实验结果综述:体性质和动力学演化

An overview of experimental results from ultra-relativistic heavy-ion collisions at the CERN LHC: bulk properties and dynamical evolution

Panagiota Foka, Malgorzata Anna Janik

摘要:

2010年底,欧洲核子研究中心大型强子对撞机(LHC)首次进行了铅核碰撞,每个核子对的质心能量为$\sqrt{s_{NN}}$ = 2.76 TeV,标志着超相对论重离子物理学新时代的开始。在运行1阶段之后,LHC还在2015年底成功地提供了碰撞能量为$\sqrt{s_{NN}}$ = 5.02 TeV的PbPb碰撞。在这些前所未有的能量下产生的热而密集的强相互作用物质的性质的研究是所有四个大型LHC实验,ALICE,ATLAS,CMS和LHCb的实验追求。这篇综述介绍了LHC运行的前三年中提供的重离子碰撞的实验结果,重点是体物质的性质和所创建的系统的动力学演化。它还介绍了第一批结果运行2重离子数据在最高的能量,以及从参考pp和pPb系统,这是重离子计划的一个组成部分的研究。

英文摘要:

The first collisions of lead nuclei, delivered by the CERN Large Hadron Collider (LHC) at the end of 2010, at a centre-of-mass energy per nucleon pair $\sqrt{s_{NN}}$ = 2.76 TeV, marked the beginning of a new era in ultra-relativistic heavy-ion physics. Following the Run 1 period, LHC also successfully delivered PbPb collisions at the collision energy $\sqrt{s_{NN}}$ = 5.02 TeV at the end of 2015. The study of the properties of the produced hot and dense strongly-interacting matter at these unprecedented energies is experimentally pursued by all four big LHC experiments, ALICE, ATLAS, CMS, and LHCb. This review presents selected experimental results from heavy-ion collisions delivered during the first three years of the LHC operation focusing on the bulk matter properties and the dynamical evolution of the created system. It also presents the first results from Run 2 heavy-ion data at the highest energy, as well as from the studies of the reference pp and pPb systems, which are an integral part of the heavy-ion programme.
