论文摘要
贝叶斯方法用于限制QCD状态方程（EOS）的密度依赖性，使用重离子碰撞（HIC）的平均横向动能和质子的椭圆流的数据在光束能量范围内，质子范围$ \ sqrt {s _ {s _ {s _ {\ mathrm {\ mathrm {nn}} = 2-10，该分析对依赖密度的EOS产生严格的限制，最大为核饱和密度的4倍。提取的EOS与在HIC实验中测得的其他可观察物以及天体物理观测的约束中得出了良好的一致性。还讨论了对可观察物的选择的敏感性。
Bayesian methods are used to constrain the density dependence of the QCD Equation of State (EoS) for dense nuclear matter using the data of mean transverse kinetic energy and elliptic flow of protons from heavy ion collisions (HIC), in the beam energy range $\sqrt{s_{\mathrm{NN}}}=2-10 GeV$. The analysis yields tight constraints on the density dependent EoS up to 4 times the nuclear saturation density. The extracted EoS yields good agreement with other observables measured in HIC experiments and constraints from astrophysical observations both of which were not used in the inference. The sensitivity of inference to the choice of observables is also discussed.
