| 抄録: | We investigate the multi-body coupling effects on the neutron star matter equation of state (EOS). By tuning the multi-body coupling constants in the relativistic mean field (RMF) models, microscopic EOSs are well fitted, and smaller neutron star radii R ∼ 12 km are obtained. When the repulsive potential for Λ at high density is assumed to have density dependence similar to that for nucleons, it is possible to support 2M☉ neutron stars by hyperonic EOSs, which do not contradict hypernuclear data. |
