从禁闭到致密QCD物质的新态

From confinement to new states of dense QCD matter

Kurt Langfeld, Andreas Wipf

摘要:

在纯杨-米尔斯理论中,中心扇区之间的跃迁与禁闭有关。我们研究的影响,这些转变的QCD类理论的中心对称性是明确打破了物质的存在。对于低温,我们提供的数值证据表明,中心过渡发生的问题只是提供一个偏向平凡的中心部门,直到中心对称性自发地打破在高温下。在SU(3)有效夸克理论中,这些跃迁对稠密强子物质的现象学后果得到了说明:中心修饰的夸克由于玻色型统计而发生凝聚,形成了迄今为止未知的稠密但冷的夸克物质状态。

英文摘要:

Transitions between centre sectors are related to confinement in pure Yang-Mills theories. We study the impact of these transitions in QCD-like theories for which centre symmetry is explicitly broken by the presence of matter. For low temperatures, we provide numerical evidence that centre transitions do occur with matter merely providing a bias towards the trivial centre sector until centre symmetry is spontaneously broken at high temperatures. The phenomenological consequences of these transitions for dense hadron matter are illustrated in an SU(3) effective quark theory: centre dressed quarks undergo condensation due to Bose-type statistics forming a hitherto unknown state of dense but cold quark matter.
