Large-Nc 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 Q2 counterterms involving the decuplet fields are constructed. We derive the correlation of the chiral parameters implied by the 1/Nc expansion at leading order in QCD.
