| English abstract | In this work we perform a detailed study of the nucleon-nucleon (NN) interaction based on relativistic mean field theory in which the potential is explicitly expressed in terms of the masses and the coupling constants of the meson fields. A unified treatment for the self-couplings of isoscalar-scalar σ meson, isoscalar-vector ω mesons, and their coupling constants is given and analytical expressions are provided. The effects of self-interacting higher order σ and ω fields on nuclear properties are evaluated. An attempt is made to explain the many-body effects which generally occur in high-density region. Both infinite and finite nuclear matter properties are discussed to investigate the behavior and sensitivity of these self interacting terms |
