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 couplin
We study S-wave interactions of the baryon decuplet with the octet of pseudoscalar mesons using the lowest order chiral Lagrangian. In the S = 1 sector, we find an attractive interaction in the โK channel with I = 1 while it is repulsive for I = 2. The attractive interaction leads to a pole in the s
