Large-N_c operator analysis of 2-body meson-baryon counterterms in the chiral Lagrangian

Abstract

The chiral SU(3) Lagrangian with the baryon octet and decuplet fields is considered. The Q^2 counterterms involving the decuplet fields are constructed. We derive the correlation of the chiral parameters implied by the 1/N_c expansion at leading order in QCD.
