Quark meson coupling model with su(3) symmetry within the Bogoliubov independent quark model of the nucleon
Abstract
We generalize the Bogoliubov quark-meson coupling model to also include hyperons. The hyperon-σ-meson couplings are fixed by the model and the hyperon-ω-meson couplings are fitted to the hypreon potentials in symmetric nuclear matter. The present model predicts neutron stars with masses above 2M and the radius of a 1.4M star equal to 13.83 km.
