论文摘要
使用手性su（3） - 含有奇迹doublet polyakov-loop-loop-hadron均值场模型CMF研究了高温和高密度QCD物质的热力学特性。 CMF模型提供了晶格QCD数据，重型离子物理和静态中子星的正确描述。讨论了恒定压力的线的行为，并讨论了重量增加。压力行为在$ __b/t \大约3 $中的快速变化表明，重子对该区域的热力学特性有很大的贡献。对于QCD压力的泰勒膨胀，该区域的位置非常接近收敛半径。还讨论了介子和不稳定的哈德子在强烈相互作用物质的流体动力扩张中的作用。
The thermodynamic properties of high temperature and high density QCD-matter are studied using the Chiral SU(3)-flavor parity-doublet Polyakov-loop quark-hadron mean-field model, CMF. The CMF model provides a proper description of lattice QCD data, heavy-ions physics, and static neutron stars. The behavior of lines of constant pressure with increase of baryon density is discussed. The rapid change of pressure behavior at $μ_B/T\approx3$ suggests a strong contribution of baryons to thermodynamic properties at this region. The position of this region is very close to the radius of convergence for a Taylor expansion of the QCD pressure. The role of mesons and unstable hadrons in the hydrodynamic expansion of strongly interacting matter is also discussed.
