Nuclear matter with scalar-vector interactions

The properties of cold nuclear matter are investigated in a class of nonlinear mean field [sigma]-[omega] theories which includes a density dependence of the meson parameters. This dependence can be both explicit and implicit through the effective nucleon mass. We apply the theory to the case of an...

Description
Summary:The properties of cold nuclear matter are investigated in a class of nonlinear mean field [sigma]-[omega] theories which includes a density dependence of the meson parameters. This dependence can be both explicit and implicit through the effective nucleon mass. We apply the theory to the case of an interaction between the scalar and the vector mesons and investigate the properties of neutron stars using the resulting equation of state.
