论文摘要
在这一贡献中，我们总结了我们最近关于手性不变质量和中子星形中的手性冷凝物的研究。我们构建了一个统一的状态方程，假设从奇偶校验模型描述的辐射物质到Quark Matter的交叉相变，由Jona-Jona-Lasinio型夸克模型。我们首先表明，从最近观察到的中子星观察到的，手性不变的质量被限制为600 meV $ \ lesssim m_0 \ Lessim $ 900 MEV。然后，我们确定跨界描述中手性冷凝物的密度依赖性，并表明手性冷凝物实际上是从核中的正性量表驱动的悬念驱动的语音物质上平稳连接的，在Quark中，Quark物质是通过夸克Dirac Sea的修改，反映了Hadron-quark crossover的Quark物质。
In this contribution, we summarize our recent studies on the chiral invariant mass and the chiral condensates in neutron star matter. We construct a unified equations of state assuming the crossover phase transition from hadronic matter described by a parity doublet model to quark matter by an Nambu--Jona-Lasinio type quark model. We first show that the chiral invariant mass is constrained to be 600 MeV $\lesssim m_0 \lesssim$ 900 MeV from recent observations of neutron stars. We then determine the density dependence of the chiral condensate in the crossover description, and show that the chiral condensates are actually smoothly connected from the hadronic matter where the change is driven by the positive chiral scalar charge in a nucleon, to the quark matter where the change is by the modification of the quark Dirac sea, reflecting the hadron-quark crossover.
