论文摘要
我们通过包括标量矢量耦合的相互作用来研究Nambu-Jona-Lasino（NJL）模型中QCD相图中的临界点。我们发现，改变这种相互作用的强度，这对QCD的真空性能没有影响，可以显着影响QCD相图中临界点的位置，尤其是Cirtal温度的值。这提供了一种使用基于NJL的传输或流体动力模型来从相对论重型离子碰撞中提取有关QCD相图的信息的方便方法。
We study the critical point in the QCD phase diagram in the Nambu-Jona-Lasino (NJL) model by including a scalar-vector coupled interaction. We find that varying the strength of this interaction, which has no effect on the vacuum properties of QCD, can significantly affect the location of the critical point in the QCD phase diagram, particularly the value of the cirtical temperature. This provides a convenient way to use the NJL-based transport or hydrodynamic model to extract information about the QCD phase diagram from relativistic heavy-ion collisions.
