论文摘要
长期以来,Quarkonium的产量一直被认为是核核碰撞核中解糊精的潜在特征。最近,通过Quark-Gluon等离子体(QGP)或相边界内的再生生产J/$ψ$的生产已被确定为解释Quarkonium Production的重要组成部分,从大型Hadron Collions(LHC)中的铅铅碰撞结果来解释Quarkonium生产结果。 Quarkonium极化也可以用于研究在LHC能量下产生的热和致密培养基的性质。在这项贡献中,将提出和讨论有关夸金族的最新爱丽丝结果。其中包括(及时和非预测)J/$ψ$和$ψ$(2s)的核修饰,以及J/$ψ$偏振,所有这些都以LHC的铅铅碰撞来衡量。结果将与可用的理论模型计算进行比较。
Quarkonium production has long been regarded as a potential signature of deconfinement in nucleus-nucleus collisions. Recently, the production of J/$ψ$ via regeneration within the quark-gluon plasma (QGP) or at the phase boundary has been identified as an important ingredient for the interpretation of quarkonium production results from lead-lead collisions at the Large Hadron Collider (LHC). Quarkonium polarization could also be used to investigate the properties of the hot and dense medium created at the LHC energies. In this contribution, the latest ALICE results on quarkonium will be presented and discussed. These include, among others, the nuclear modifications of (prompt and non-prompt) J/$ψ$ and $ψ$(2S) production, and the J/$ψ$ polarisation, all measured with lead-lead collisions at the LHC. The results will be compared with available theoretical model calculations.
