论文摘要
我们报告了在$ \ sqrt {s_ {nn}} $ = 54.4 GEV在相对论重的重离子碰撞器（RHIC）记录的GEV中，在Au+Au碰撞中创建的系统的系统测量值。 $π^{\ pm} $，$ k^{\ pm} $的横向动量光谱和$ p $（$ \ bar {p} $）在不同中心性类别中以中高率$（\ lvert y \ rvert <0.1）$进行了研究。我们还提出了粒子的中期测量值，在$ \ sqrt {s_ {nn}} $ = 54.4 GEV时，AU+AU碰撞中的$（DN/DY）$和粒子比率。动力学冻结参数（$ t_ {kin} $和$ \langleβ\ rangle $）是使用Blast-Wave模型从粒子光谱中提取的，所有结果均与先前发布的实验结果进行了比较。
We report systematic measurements of bulk properties of the system created in Au+Au collisions at $\sqrt{s_{NN}}$ = 54.4 GeV recorded by the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The transverse momentum spectra of $π^{\pm}$, $K^{\pm}$, and $p$($\bar{p}$) are studied at mid-rapidity $(\lvert y \rvert < 0.1)$ for different centrality classes. We also present mid-rapidity measurement of particle yields $(dN/dy)$ and particle ratios in Au+Au collisions at $\sqrt{s_{NN}}$ = 54.4 GeV. The kinetic freeze-out parameters ($T_{kin}$ and $\langle β\rangle$) are extracted from particle spectra using the blast-wave model, and all the results are compared with previously published experimental results.
