通过测量高$p_T$强子在重离子碰撞中的动量损失分数详细研究部分子能量损失

Detailed study of parton energy loss via measurement of fractional momentum loss of high $p_T$ hadrons in heavy ion collisions

Takao Sakaguchi

摘要:

本文介绍了用PHENIX测量高$p_T$鉴别强子的动量损失分数($d p_T/p_T$)的结果。从39GeV Au+Au到2.76TeV Pb+Pb计算的高$p_T$ pizero的$d p_T/p_T$变化为6倍。我们绘制了$d p_T/p_T$与几个全局变量$N_{part}$、$N_{qp}$和$dN/deta$的关系图,并找到了全局特征。发现当$d p_T/p_T$对$dN/deta$作图时,200 GeV Au+Au点与中心2.76 TeV Pb+Pb点合并。

英文摘要:

PHENIX measurement of the fractional momentum loss ($d p_T/p_T$) of high $p_T$ identified hadrons are presented. The $d p_T/p_T$ of high $p_T$ pizero which are computed from 39GeV Au+Au over to 2.76TeV Pb+Pb are found to vary by a factor of six. We plotted the $d p_T/p_T$ against several global variables, $N_{part}$, $N_{qp}$ and $dN/deta$, and found global features. It was found that 200GeV Au+Au points are merging into the central 2.76TeV Pb+Pb points when plotting $d p_T/p_T$ against $dN/deta$.
