✦ Synopsis

We present a chiral-invariant SU(3) Lagrangian describing the interactions of the baryon octet with the lowest-mass meson nonets. Empirical estimates for the strengths of these vertices are given. The nonlinear realization of the chiral symmetry generates pair-meson interaction vertices, the coupling constants for which contain no new free parameters. A baryon-baryon potential is evaluated and its quality is examined for the NN sector.

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 e
