Contribution

It formulates a new quark-meson coupling model grounded in Bogoliubov's nucleon model and applies it to symmetric nuclear matter.

Findings

Predicts compressibility K=249 MeV at saturation density

Calculates quark effective mass m_q^*=249.1 MeV

Estimates nucleon mass radius r=0.93 fm

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 a phenomenological description of symmetric nuclear matter. The model predicts, at saturation density, the compressibility $K=249$ MeV and the quark effective mass $m_q^*= 249.1$ MeV, {the effective nucleon mass being $M^*=747.3$ MeV}. The predicted nucleon mass radius is $r=0.93$ fm.
