摘要:

在最近发展起来的Polyakov-Nambu-Jona-Lasinio模型的扩展框架下,我们分析了夸克化学势为零时强相互作用粒子系统的物理性质.除了八个夸克相互作用项,非正则项,明确打破手征对称性,以相同的顺序在$1/N_c$展开($N_c$颜色数)包括在内。最近提出的Polyakov势被认为是一个有利的情况下,最近的模型变体的结果进行比较,格点量子色动力学数据。

英文摘要:

We analyze the thermodynamical properties of a system of strongly interacting particles at vanishing quark chemical potential in the framework of a recently developed extension of the Polyakov-Nambu-Jona-Lasinio Model. In addition to eight quark interactions terms, non-canonical terms which explicitly break chiral symmetry up to the same order in a $1/N_c$ expansion ($N_c$ number of colors) are included. A recently proposed Polyakov potential is considered and the results are compared to lattice QCD data resulting in a favorable scenario for the recent model variants.
