NN POTENTIAL FROM CHIRAL SU(3) LAGRANGIAN

We present a chiral-invariant SU(3) Lagrangian describing the interact ions 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 v ertices, the coupling constants for which contain no new free paramete rs. A baryon-baryon potential is evaluated and its quality is examined for the NN sector.
