Systematic correlation analysis between the nuclear matter parameters and neutron star properties within relativistic mean-field theory

Motivated by constraining the neutron star properties and eliminating their uncertainties based on the constraints on nuclear matter parameters extracted from the terrestrial experiments, the correlations between a mount of nuclear matter parameters and neutron star properties have been analyzed by the selected equation of states within the relativistic mean-field theory and used to constrain the neutron star properties. It is found that the radius R, tidal deformability A, and other neutron star properties have a notable correlation with the slope of symmetry energy L for the typical neutron stars, and the R1.4 and A1.4 restricted by the constraint on L = 54 +/- 8 MeV can be consistent with the GW170817 and NICER observation constraints. Furthermore, it is shown that L also has a good correlation with the properties of low-mass neutron stars, such as the gravitational binding energy IEgI. The IEgI of low-mass neutron stars can be theoretically well constrained with the constraint range of L.
