▪摘要回顾了重离子碰撞中J/ψ和ψ '产生的数据及其解释，特别强调了最近报道的Pb-Pb反应中的异常。根据预介子的末态吸收和初始态部分子散射引起的pT分布，讨论了在pA碰撞中观察到的抑制。描述了实验装置，并给出了J/ψ和ψ’抑制的各种结果，包括它们的pt依赖性。根据所提出的夸克-胶子等离子体形成和通过共动器抑制的观点，讨论了数据，特别是观测到的Pb-Pb碰撞中的异常抑制。
▪ Abstract Data and their interpretations are reviewed for J/ψ and ψ′ production in heavy-ion collisions with particular emphasis on the recently reported anomaly in Pb-Pb reactions. The observed suppressions in pA collisions are discussed in terms of final-state absorption of a pre-meson and the pT distributions due to parton scattering in the initial state. The experimental setup is described and the various results for J/ψ and ψ′ suppressions, including their pT-dependence, are presented. The data, in particular the observed anomalous suppression in Pb-Pb collisions, are discussed in the light of the proposed ideas, among them quark-gluon plasma formation and suppression via co-movers.
