NN interactions in the extended chiral SU(3) quark model Original Research Article

The chiral SU(3) quark model is extended to include coupling between vector chiral field and quarks. By using this model, the phase shifts of NN scattering for different partial waves are studied. The results are very similar to those of the chiral SU(3) quark model calculation, in which one gluon exchange (OGE) plays dominate role in the short range part of the quark–quark interactions. Only in the View the MathML source case, the one channel phase shifts of the extended chiral SU(3) quark model are obviously improved.
