摘要:

在这项工作中,我们利用AGS、SPS和RHIC能量下核碰撞中产生的$ϕ$介子的实验结果提取了QCD状态方程(EoS)。数据面临着简单的热力学期望和晶格结果。实验数据表明一级相变,与混合相拉伸能量密度之间的$\sim$ 1和3.2 GeV/ $fm^3$。

英文摘要:

In this work, we extract the QCD Equation of State (EoS) using experimental results of the $ϕ$ meson produced in nuclear collisions at AGS, SPS and RHIC energies. The data are confronted to simple thermodynamic expectations and lattice results. The experimental data indicate a first order phase transition, with a mixed phase stretching energy density between $\sim$ 1 and 3.2 GeV/$fm^3$.
