  • We propose the new quark mean-field bag (QMFB) model by incorporating the bag confinement mechanism in the original quark mean-field model. The properties of nuclear matter and neutron star are studied with QMFB. For the study of the bag effect, we newly fit 12 new parameter sets by reproducing the empirical saturation properties of nuclear matter. Quark confinement is found to be mainly demonstrated by the bag after it is included in the model, instead of the confining potential. For nuclear… CONTINUE READING
