标题： J/psi production at RHIC-PHENIX

摘要： J/psi被认为是在相对论重离子碰撞中产生的去禁闭夸克胶子等离子体（QGP）中最重要的探针之一。 尽管J/psi被认为在QGP中通过德拜色屏蔽而解离，但来自冷核物质（CNM）、激发态底夸克（chi_c和psi'）和底夸克的级联效应以及来自未关联的魅夸克的再生成存在竞争效应。 本文介绍了可以提供信息以区分这些效应的测量结果。 显示英文摘要

摘要： The J/psi is considered to be among the most important probes for the deconfined quark gluon plasma (QGP) created by relativistic heavy ion collisions. While the J/psi is thought to dissociate in the QGP by Debye color screening, there are competing effects from cold nuclear matter (CNM), feed-downs from excited charmonia (chi_c and psi') and bottom quarks, and regeneration from uncorrelated charm quarks. Measurements that can provide information to disentangle these effects are presented in this paper.
