Relativistic mean field model for nuclear matter with non-linear derivative couplings

We apply the non-linear derivative (NLD) model proposed recently by Gaitanos et al. to investigate the properties of nuclear matter and the mass-radius relation of neutron stars as well. Three cases with different energy-dependent non-linear terms in this model are chosen, in which comparison among the obtained results has been made. It is found that the calculated results are sensitive to the non-linear terms in the NLD model.
