The effect of hyperon-meson coupling in infinite nuclear matter

In this work, we provide the relativistic mean field investigation of the neutron star properties by using various hyperon-meson coupling to the recently developed G2 force parameter. It is to be noted that the model used here for the study of the EoS of the hyper-nuclear matter is the effective Lagrangian (E-RMF), the extension of the standard relativistic mean field (RMF) model. From the Lagrangian, we derive the equation of motion for σ, ω and ρ-mesons fields and solve it in the mean field approximation self consistently. Further, we derive the energy and pressure density along with all meson field equations analytically by self-consistent numerical iterative methods
