论文摘要
Baryon-number敏感性与实验中获得的波动相关，我们可以从理论上计算敏感性并将其与实验波动数据进行比较。在本文中，我们计算了来自Polyakov-loop扩展的Nambu-Jona-lasinio（PNJL）模型的Baryon-number敏感性，然后将它们与重离子碰撞实验波动数据以及其他模型的结果进行比较，以及其他模型，Lattice QCD和Lattice QCD和Dyson-Schwinger方程（DSES）方法。我们的结果符合实验，并且与实验点DSE的结果非常相似，这表明PNJL模型适合研究此问题。
The baryon-number susceptibilities is correlated to the fluctuations obtained in experiments, we can theoretically calculate the susceptibility and compare it with the experimental fluctuations data. In this paper, we calculate the baryon-number susceptibilities from the Polyakov-loop-extended Nambu-Jona-Lasinio (PNJL) model, then compare them with the the heavy ion collision experimental fluctuation data and the results from other models, lattice QCD and the Dyson-Schwinger equations (DSEs) approach. Our results are in line with the experiment and very similar to the results of DSEs at experimental points, which shows that the PNJL model is suitable for studying this issue.
