论文摘要
我们根据从sqrt {s_ {nn}} = 11.5 GEV到5.02 TEV的碰撞能量中测量的恒星和爱丽丝的粒子产量，对化学冷冻温度（T_CH）进行了计算。使用热拳头强体共振气体模型采用大型典型的集合方法，我们显示了在QCD相图的跨界区域中依赖风味的化学冷冻输出的证据。在消失的男化学潜力下，我们分别计算出光和奇怪的风味冻结温度T_L = 150.2 +-2.6 MeV和T_S = 165.1 +-2.7 MeV。
We present calculations of the chemical freeze-out temperature (T_ch) based on particle yields from STAR and ALICE measured at collision energies ranging from sqrt{s_{NN}} = 11.5 GeV to 5.02 TeV. Employing the Grand Canonical Ensemble approach using the Thermal-FIST Hadron Resonance Gas model package, we show evidence for a flavour-dependent chemical freeze-out in the crossover region of the QCD phase diagram. At a vanishing baryochemical potential, we calculate light and strange flavour freeze-out temperatures T_L = 150.2 +- 2.6 MeV and T_S = 165.1 +- 2.7 MeV, respectively.
