摘要:
采用SU(2)手征对称性自发破缺的非线性实现模型,研究中子星物质的组成及中子星的宏观性质发现手征对称性自发破缺对于中子星的成分有一定程度的影响,这种效应使重子数密度较高时的单核子能量降低约10 MeV,有效质量下降约20 MeV.研究结果表明,该效应对中子星物质有“软化”作用,使中子星质量有一定降低.
Abstract:
The composition of neutron stars and their properties are studied via the SU (2) non-linear chiral symmetry spontaneous breaking(CSB ) model. The composition of neutron star matter is influenced by the CSB effect. The CSB effect,in high baryon number density regions,lowers the single nucleon energy and effective mass by 10 MeV and 20 Mev, respectively. The results imply the CSB effect can“soften" neutron star matter. And CSB also lowers the mass of the neutron star.
