LARGE-NC HIGHER-ORDER CHIRAL LAGRANGIAN FOR NONLEPTONIC WEAK-INTERACTIONS

Based on factorization and bosonization of quark currents derived from the large-NC effective p4 nonanomalous chiral Lagrangians for low-energy strong interactions determined by the integration of nontopological chiral anomalies with first-order gluonic corrections being treated as a free parameter, we obtain a large-Nc effective Lagrangian for nonleptonic S=1 weak interactions at order p4. The decay is then employed as a profound example for testing the higher-order chiral Lagrangians. © 1990 The American Physical Society.
