Abstract

An effective theory of large-N-C QCD of pseudoscalar, vector, and axial-vector mesons has been used to study six K-14 decay modes. It has been found that the matrix elements of the axial-vector current dominate the K-14 decays. PCAC is satisfied. A relationship between three form factors of the axial-vector current has been predicted. Partial-wave analysis has been door. Non-zero phase shifts: are originated in rho --> pi pi. The decay rates arecalculated in the chiral limit. In this study there is no adjustable parameter.
