Findings

Predicts incompressibility K=335.17 MeV at saturation density

Finds effective quark mass m_q^*=238.5 MeV and nucleon mass ratio M^*/M=0.76

Models neutron stars with masses above two solar masses

Abstract

The quark-meson coupling model due to Guichon is formulated on the basis of the independent quark model of the nucleon proposed by Bogoliubov and is applied to the phenomenological descriptions of symmetric and asymmetric nuclear matter. For symmetric matter, the model predicts, at saturation density, the incompressibility $K=335.17$ MeV, the quark effective mass $m_q^*=238.5$ MeV, and the effective nucleon mass $M^*= 0.76 M,$ where $M$ is the nucleon mass in vacuum. Neutron star massesabove two solar masses are obtained.
