Quark mean field model for nuclear matter and finite nuclei
We study nuclear matter and finite nuclei in terms of the quark mean field (QMF) model, in which we describe the nucleon using the constituent quark model. The meson mean fields, in particular the σ meson, created by other nucleons act on quarks inside a nucleon and change the nucleon properties in nuclear medium. The QMF model predicts an increasing size of the nucleon as well as a reduction o...
متن کاملSaturation properties of nuclear matter in a relativistic mean field model constrained by quark dynamics
We have built an effective Walecka-type hadronic Lagrangian in which the hadron masses and the density dependence of the coupling constants are deduced from the quark dynamics using a Nambu-Jona-Lasinio model. The parameters of this Nambu-Jona-Lasinio model have been determined using the meson properties in the vacuum but also in the medium through the omega meson mass in nuclei measured by the...
متن کاملModified 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 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 کاملNuclear matter properties in relativistic mean field model with nucleon volume extensions
In relativistic field models nucleons and mesons are all regarded as point-like particles. These models can be used to describe main properties of nuclear matter. In fact, however, a nucleon has a definite size. It is wellknown that in standard state of nuclear matter, the total volume occupied by all nucleons is about ten percent of the volume of nuclear matter. In the conditions of extreme hi...
