论文摘要
我们研究了夸克 - 杜伦等离子体〜（QGP）在低温和大型化学电位下在低温下引起的密度波动（QGP）。我们分析了净 - 巴里昂数字峰度和偏度的结构，并详细介绍了它们与核液体〜（LG）相变的关系和高于临界温度高于临界温度以上的HADRONIC相互作用。结合RHIC/NICA/FAIR/J-PARC/HIAF的相关实验项目，以及从$ 200 \，$ GEV到$ 1.8 \，$ GEV的碰撞能量，我们提出了峰峰结构（Skewness）的双峰结构（SKEWNESS）作为碰撞能量的函数，可以将其识别为识别核液体相位过渡和核液体阶段。特别是，低温下的波动分布提供了一种探索har子相互作用和核液体气体过渡的新方法。
We investigate the density fluctuations induced by hadronic interactions at low temperatures and large chemical potentials after the hadronization of quark-gluon plasma~(QGP). We analyze the structures of net-baryon number kurtosis and skewness and elaborate on their relations with the nuclear liquid-gas~(LG) phase transition and hadronic interactions above the critical temperature. Combining with the relevant experimental projects at RHIC/NICA/FAIR/J-PARC/HIAF with collision energies from $200\,$GeV to $1.8\,$GeV, we propose a double-peak structure of kurtosis (skewness) as a function of collision energy, which can be taken to identify the chiral phase transition and the nuclear liquid-gas phase transition. In particular, the fluctuation distributions at low temperatures provide a new method to explore hadronic interactions and nuclear liquid-gas transition.
