原中子星物质的退禁闭相变

The Deconfinement Phase Transition in Proto-Neutron-Star Matter

J. Roark, V. Dexheimer

摘要:

在这项工作中,我们详细研究了在中子星和原中子星(其中轻子分数是固定的)的背景下,在热/密核物质中发生的退禁闭相变。在每种情况下,被认为是不同的混合物的相位与不同的本地和全球保守量的可能性。为此,手征平均场(CMF)模型,一个有效的相对论模型,包括自洽的手征对称性恢复和解除禁闭的夸克物质,被采用。最后,我们比较了我们的结果与PQCD提供的数据在不同的温度和条件。

英文摘要:

In this work, we study in detail the deconfinement phase transition that takes place in hot/dense nuclear matter in the context of neutron stars and proto-neutron stars (in which lepton fraction is fixed). The possibility of different mixtures of phases with different locally and globally conserved quantities is considered in each case. For this purpose, the Chiral Mean Field (CMF) model, an effective relativistic model that includes self-consistent chiral symmetry restoration and deconfinement to quark matter, is employed. Finally, we compare our results with data provided by PQCD for different temperatures and conditions.
