Exploring the role of model parameters and regularization procedures in the thermodynamics of the PNJL model
摘要：
在Polyakov-Nambu-Jona-Lasinio模型的背景下研究了状态方程和临界端点附近的临界行为。我们证明了一个方便的选择的模型参数是至关重要的等熵轨迹得到正确的描述。与一般热力学要求的协议，正则化程序的影响的物理相关性是保险。结果与简单的热力学预期和晶格数据进行了比较。
英文摘要：
The equation of state and the critical behavior around the critical end point are studied in the context of the Polyakov--Nambu--Jona--Lasinio model. We prove that a convenient choice of the model parameters is crucial to get the correct description of isentropic trajectories. The physical relevance of the effects of the regularization procedure is insured by the agreement with general thermodynamic requirements. The results are compared with simple thermodynamic expectations and lattice data.
