An overview of experimental results from ultra-relativistic heavy-ion collisions at the CERN LHC: hard probes

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目前由所有四个大型LHC实验ALICE,ATLAS,CMS和LHCb进行实验研究。在大型强子对撞机的碰撞能量的增加超过10倍,相对于以前实现的最大能量在其他对撞机设施,在硬探针的生产率增加的结果。这篇评论介绍了选定的实验结果,重点是探测硬过程中的重离子碰撞在LHC运行的前三年交付的可观的。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. The study of the properties of the produced hot and dense strongly-interacting matter at these unprecedented energies is currently experimentally pursued by all four big LHC experiments, ALICE, ATLAS, CMS, and LHCb. The more than a factor 10 increase of collision energy at LHC, relative to the previously achieved maximal energy at other collider facilities, results in an increase of production rates of hard probes. This review presents selected experimental results focusing on observables probing hard processes in heavy-ion collisions delivered during the first three years of the LHC operation. 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.
