Properties of neutron star matter based onmodern baryon-baryon interactions

本文在微观重子-重子相互作用的基础上研究了实现为中子星的高密度重子物质的结构。结果表明，手征有效场理论与三核子力的相互作用可以定量地理解核物质的基本饱和性质。σ和Xi超子由于它们的排斥势而不太可能出现在中子星星物质中。研究了λ超子可能的三体力效应，这是理解最近观测到的大质量中子星星所必需的。

Structures of high densitybaryonicmatter realized as a neutron starare studiedon the basis of microscopic baryon-baryon interactions. It is shownthat the fundamental saturation property of nuclearmatter is understood quantitatively by the interaction of the chiral effective field theorywith three-nucleon forces. Sigma and xi hyperons are unlikely to appear in neutron star matter because of their repulsive potentials. Possible three-body force effectsfor lambda hyperonareinvestigated, which are needed to understand the massive neutron star recently observed.
