论文摘要
中央金金（AU-AU），铅铅（PB-PB），氩变速器（AR-KCL）（AR-KCL）和镍 - 尼克（Ni-Ni）（Ni-Ni）在这项工作中已经研究了宽的能源碰撞的中央金金（AU-AU），铅铅（PB-PB），铅铅（PB-PB），铅铅（PB-PB），铅铅（PB-PB），铅铅（PB-PB），铅铅（PB-PB），铅铅（PB-PB）中的多震动和非阵锋（即其他已识别的）颗粒的横向动量（质量）光谱。已经分析了通过各种合作衡量的实验数据。带有Tsallis统计的BLAST波拟合用于从横向动量（质量）光谱的实验数据中提取动力学冷冻温度和横向流速。提取的参数随着碰撞能量的增加而增加，并随着相对论重离子对撞机（RHIC）处的光束能量扫描（BES）能量的饱和趋势而出现。这种饱和度意味着部分解解的相变能量为7.7 GEV，整个解解的发作为39 GEV。此外，对于多种震动和其他已鉴定的粒子，观察到动力学冻结场景的能量扫描/依赖性，尽管对于各种粒子也观察到了多个冻结场景。
The transverse momentum (mass) spectra of the multi-strange and non-multi-strange (i.e. other identified) particles in central gold-gold (Au-Au), lead-lead (Pb-Pb), argon-muriate (Ar-KCl) and nickel-nickel (Ni-Ni) collisions over a wide energy range have been studied in this work. The experimental data measured by various collaborations have been analyzed. The blast-wave fit with Tsallis statistics is used to extract the kinetic freeze-out temperature and transverse flow velocity from the experimental data of transverse momentum (mass) spectra. The extracted parameters increase with the increase of collision energy and appear with the trend of saturation at the Beam Energy Scan (BES) energies at the Relativistic Heavy Ion Collider (RHIC). This saturation implies that the onset energy of phase transition of partial deconfinement is 7.7 GeV and that of whole deconfinement is 39 GeV. Furthermore, the energy scan/dependence of kinetic freeze-out scenarios are observed for the multi-strange and other identified particles, though the multiple freeze-out scenarios are also observed for various particles.
