双味夸克物质的Phase diagram:非零温度下的胶子相

Phase diagram of two-flavor quark matter: Gluonic phase at nonzero temperature

O. Kiriyama

摘要:

研究了非零温下中性双味夸克物质的相结构。我们的分析是在规范的Nambu-Jona-Lasinio模型和平均场近似的框架内进行的。我们用自洽的方法计算了胶子相(胶子柱相II)的自由能,并研究了从胶子相到2SC/g2 SC/NQ相的相变.我们简要地考虑了耦合强度-温度平面上的相图,并讨论了由正常夸克相和2SC相组成的混合相。

英文摘要:

The phase structure of neutral two-flavor quark matter at nonzero temperature is studied. Our analysis is performed within the framework of a gauged Nambu--Jona-Lasinio model and the mean-field approximation. We compute the free energy of the gluonic phase (gluonic cylindrical phase II) in a self-consistent manner and investigate the phase transition from the gluonic phase to the 2SC/g2SC/NQ phases. We briefly consider the phase diagram in the plane of coupling strength versus temperature and discuss the mixed phase consisting of the normal quark and 2SC phases.
