论文摘要
重离子碰撞时强子产量的波动测量可以重现QCD物质的相变参数。波动结果在该区域中产生的准确参数($μ_b$)附近的准确参数非常敏感。在这项工作中,使用强子共振气体模型(HRG),我们使用单个波动结果确定了黑龙的冻结温度,并发现在QCD相变附近零$μ_b$的QCD期间的顺序冻结取决于产生的Hadronic物种的质量。利用最近发布的净$λ$波动的结果和其他一些波动结果,我们研究了低雄性化学势和质量中心能量的相图,范围从19.6-200 GEV/$ c^2 $,找到大量的定量证据,以支持我们的主张。
Fluctuation measurements of hadron yields at heavy-ion collisions can reproduce the phase transition parameters of QCD matter. The fluctuation results produce accurate parameters near zero baryonic chemical potential($μ_B$) being very sensitive in that region. In this work, using the Hadron Resonance Gas Model(HRG), we determine the freeze-out temperatures of the hadrons using individual fluctuation results and find that sequential freeze-out of hadrons during the QCD phase transition near zero $μ_B$ is dependent on the mass of produced hadronic species. Using recently published results of net-$Λ$ fluctuations and some other fluctuation results, we study the phase diagram at low baryonic chemical potential and center-of-mass energies ranging from 19.6 - 200 GeV/$c^2$ and find significant, quantitative evidence to support our claim.
