Saturation properties of nuclear matter in a relativistic mean field model constrained by quark dynamics

چکیده

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 TAPS collaboration. Realistic properties of nuclear matter have been obtained.

We derive a microscopic relativistic point-coupling model of nuclear many-body dynamics constrained by in-medium QCD sum rules and chiral symmetry. The effective Lagrangian is characterized by density dependent coupling strengths, determined by chiral oneand two-pion exchange and by QCD sum rule constraints for the large isoscalar nucleon self-energies that arise through changes of the quark co...

A new nonlinear mean-eld model of strange hadronic matter¤

The derivative scalar-coupling (DSC) model of relativistic nuclear matter by Zimanyi and Moszkowski is reconsidered from a constituent quark picture of nucleons. The DSC can be regarded as a correction to  coupling owing to the e¤ect of scalar mean-…eld on the constituent quark. By a little revision of the DSC model, we …nd a new model that can reproduce the nuclear matter saturation propert...

  One of the most interesting application of the many-body methods to the nuclear physics is the calculation of the properties of the nuclear matter, especially its binding energy. In this paper, we have studied the influence of Δ -isobar on the properties of the symmetrical nuclear matter using the lowest order constrained variational (LOCV) method with the V28 potential. It is shown that the ...
