Extension of the derivative scalar coupling model to strange hadronic matter based on a constituent quark picture of baryons

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 NNsigma coupling owing to the effect of scalar mean-field on the constituent quark. By a little...

description 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 NNsigma coupling owing to the effect of scalar mean-field on the constituent quark. By a little revision of the DSC model, we find a new model that can reproduce the nuclear matter saturation properties as well as the Dirac-Brueckner-Hartree-Fock model. This model is readily extended to hyperons and then is applied to investigate the strange hadronic matter. It predicts the same meta-stable state as the nonlinear scalar and vector coupling model or the modified quark-meson coupling model.
