PHENIX实验中夸克偶素的最新研究

Recent Quarkonia Studies from the PHENIX Experiment

J. M. Durham

摘要:

核-核碰撞中的夸克偶素抑制是探测重离子碰撞产生的介质密度和温度的有力工具。$p(d)$ +Au碰撞中的前向快度测量对于理解夸克偶子态如何受到初态效应、形成时间和局部粒子多重性的影响是必不可少的。在Au+Au碰撞中的早期测量显示,与中快度结果相比,前向$J/ψ$的抑制更强,表明再生夸克偶素态在前向快度中的贡献可能更小。这些会议记录报告了PHENIX合作在快度范围$1.2<|y|<2.2$进行的最新夸克偶素研究。

英文摘要:

Quarkonia suppression in nucleus-nucleus collisions is a powerful tool to probe the density and temperature of the medium created in heavy ion collisions. Forward rapidity measurements in $p(d)$+Au collisions are essential to understand how quarkonia states are affected by initial state effects, formation time, and local particle multiplicity. Earlier measurements in Au+Au collisions showed a stronger suppression of forward $J/ψ$ compared to mid-rapidity results, indicating the possibility of a smaller contribution of regenerated quarkonia states at forward rapidity. These proceedings report on the latest quarkonia studies performed by the PHENIX collaboration in the rapidity range $1.2<|y|<2.2$.
