化学平衡下的退禁闭相变

Deconfinement Phase Transition under Chemical Equilibrium

Veronica Dexheimer, Krishna Aryal, Madison Wolf, Constantinos Constantinou, Ricardo L. S. Farias

摘要:

在这项工作中,我们研究如何与轻子化学平衡的假设影响解除禁闭的相变夸克物质。这是在手征平均场模型(CMF)的框架内完成的,允许非零净奇异性,对应于天体物理学场景中发现的条件。我们用温度、重子化学势、电荷或同位旋分数或化学势建立了三维QCD相图,以显示在化学平衡的特殊情况下,例如在冷催化中子星内部建立的情况下,退禁闭区域如何坍缩成一条线。

英文摘要:

In this work, we investigate how the assumption of chemical equilibrium with leptons affects the deconfinement phase transition to quark matter. This is done within the framework of the Chiral Mean Field model (CMF) allowing for non-zero net strangeness, corresponding to the conditions found in astrophysical scenarios. We build 3-dimensional QCD phase diagrams with temperature, baryon chemical potential, and either charge or isospin fraction or chemical potential to show how the deconfinement region collapses to a line in the special case of chemical equilibrium, such as the one established the interior of cold catalyzed neutron stars.
