论文摘要
基于重子的有效尺寸的单品味排除 - 体积模型再现了GW170817最新研究所需的状态方程（EOS）的硬柔软密度演变。这种现象学模型基本上实现了夸克的概念，该概念是从大$ n_ {c} $仪表理论中引入的。增强的核子相互作用和动态生成的夸克自由度可以重现EOS的硬性演变。在本文中，我们通过考虑电磁电荷和可能的弱平衡来将排除的体积模型扩展到三种风味系统，以便获得适当的描述，以了解从重力波观测中推断出的EOS的硬柔软行为。
The single-flavor excluded-volume model based on the effective size of baryons reproduces the hard-soft density evolution of the equation of state (EoS) required by the recent studies of GW170817. This phenomenological model basically realizes the concept of quarkyonic matter which is introduced from large-$N_{c}$ gauge theory for dense matter. Enhanced nucleon interactions and dynamically generated quark degrees of freedom can reproduce the hard-soft evolution of the EoS. In this paper, we extend the excluded-volume model to a three-flavor system by considering electromagnetic charge and possible weak equilibrium in order to obtain a proper description for the hard-soft behavior of the EoS inferred from the gravitational waves observations.
