强子和夸克-强子模型中的致密星

Compact Stars in Hadron and Quark-Hadron Models

S. Schramm, V. Antocheviz Dexheimer

摘要:

我们采用基于手征对称性非线性实现的味SU(3)方法和强子味SU(2)宇称偶重态模型研究了强相互作用致密物质和中子星。我们研究了恒星物质的手征对称性恢复和物态方程,并利用不同的自由度确定了中子星的性质。最后,我们在模型方法中包括夸克。我们显示了由此产生的相图以及混合星解决方案,这个模型。

英文摘要:

We investigate strongly interacting dense matter and neutron stars using a flavor-SU(3) approach based on a non-linear realization of chiral symmetry as well as a hadronic flavor-SU(2) parity-doublet model. We study chiral symmetry restoration and the equation of state of stellar matter and determine neutron star properties using different sets of degrees of freedom. Finally, we include quarks in the model approach. We show the resulting phase diagram as well as hybrid star solutions for this model.
