2023-12-22 Difference between neutron and proton effective masses as a function of the baryon density. doi:10.57760/sciencedb.j00186.00359 en In the nonlinear relativistic mean field model, the isospin splitting of the effective nucleon mass is primarily determined by the coupling strength of the $\delta$ meson. The large coupling strength of the $\delta$ meson results in large isospin splitting of the effective nucleon mass. When the coupling strength of the $\delta$ meson is zero (set1), there is no isospin splitting of the effective nucleon mass. effective nucleon mass; relativistic mean field; coupling strength 韦斯纳 PUBLIC https://creativecommons.org/publicdomain/zero/1.0/ dataset http://www.doi.org/10.1007/s41365-024-01380-x Science Data Bank
