Modified quark-meson coupling model for nuclear matter.
The quark-meson coupling model for nuclear matter, which describes nuclear matter as non-overlapping MIT bags bound by the self-consistent exchange of scalar and vector mesons, is modified by introducing medium modification of the bag constant. We argue that the bag constant should decrease with increasing density as a consequence of partial chiral symmetry restoration in nuclear medium. We mod...
متن کاملNuclear Matter Properties of the Modified Quark Meson Coupling Model
We explore in more detail the modified quark meson coupling (MQMC) model in nuclear matter. Based on previous studies two different functional forms for the density dependence of the bag constant are discussed. For uniform matter distributions the MQMC model can be cast in a form identical to QHD by a redefinition of the sigma meson field. It is then clear that modifications similar to those in...
متن کاملA Quark-meson Coupling Model for Nuclear and Neutron Matter
An explicit quark model, based on a mean eld description of non-overlapping nucleon bags bound by the self-consistent exchange of , ! and mesons, is used to investigate the properties of both nuclear and neutron matter. We establish a clear understanding of the relationship between this model, which incorporates the internal structure of the nucleon, and QHD. Finally, we use the model to study ...
متن کاملHot Nuclear Matter in the Quark Meson Coupling Model
We study here hot nuclear matter in the quark meson coupling (QMC) model which incorporates explicitly quark degrees of freedom, with quarks coupled to scalar and vector mesons. The equation of state of nuclear matter including the composite nature of the nucleons is calculated at finite temperatures. The calculations are done taking into account the medium–dependent bag constant. Nucleon prope...
