摘要
总结了RHIC能区质子-质子和重离子碰撞中粲物理的研究和进展.介绍了RHIC-STAR上开粲与粲偶素测量的最新成果.在从实验上验证QCD理论,理解重味夸克与介质相互作用,解释开粲与粲偶素不同的产生机制等方面都有重要的价值,并帮助我们研究和理解重离子碰撞产生的QGP新物质形态的基本特性.
The overview of charm physics in p+p and heavy-ion collisions at RHIC energy is summarized.The latest results of open charm and charmonium production from RHIC-STAR experiment are presented,which are valuable for testing QCD theory via experiment,understanding the interactions between heavy quark and medium,exploring the different production mechanisms of open charm and charmonium.The measurements renew our knowledge of the fundamental properties of the QGP matter created in heavy-ion collisions.
