热格点量子色动力学中的冷夸克星

Cold quark stars from hot lattice QCD

R. Schulze, B. Kampfer

摘要:

基于β稳定电中性退禁闭物质的准粒子模型,讨论了纯夸克星的质量-半径关系。该模型是调整到最近的热格点量子色动力学结果为2 + 1味几乎物理夸克质量。我们发现相当小的半径和质量的平衡配置组成的冷deconfined物质,以及区别于中子或混合星。

英文摘要:

Based on a quasiparticle model for βstable and electrically neutral deconfined matter we address the mass-radius relation of pure quark stars. The model is adjusted to recent hot lattice QCD results for 2 + 1 flavors with almost physical quark masses. We find rather small radii and masses of equilibrium configurations composed of cold deconfined matter, well distinguished from neutron or hybrid stars.
