WebbThe relativistic mean field (RMF) model of the nuclear matter equation of state was modified by including the effect of Pauli-blocking owing to quark exchange between the baryons. Different schemes of a chiral enhancement of the quark Pauli blocking was suggested according to the adopted density dependence of the dynamical quark mass. … http://atlas.physics.arizona.edu/~shupe/Indep_Studies_2015/Notes_Goethe_Univ/B11_QuarkModel.pdf
