用非广延MIT袋模型重新研究夸克物质

Quark matter revisited with non extensive MIT bag model

Pedro H. G. Cardoso, Tiago Nunes da Silva, Airton Deppman, Débora P. Menezes

摘要:

在这项工作中,我们重新审视了麻省理工学院袋模型来描述夸克物质在通常的费米-狄拉克和Tsallis统计。我们通过分析QCD相图的一级相变和恒星物质性质两种不同的图像来验证后者的非加性效应。然而,QCD相图在视觉上受到Tsallis统计的影响,对夸克星宏观性质的影响几乎没有注意到。

英文摘要:

In this work we revisit the MIT bag model to describe quark matter within both the usual Fermi-Dirac and the Tsallis statistics. We verify the effects of the non-additivity of the latter by analysing two different pictures: the first order phase transition of the QCD phase diagram and stellar matter properties. While, the QCD phase diagram is visually affected by the Tsallis statistics, the resulting effects on quark star macroscopic properties are barely noticed.
