Abstract
An effective theory of large-N-C QCD of pseudoscalar, vector, and axial-vec tor mesons has been used to study six K-14 decay modes. It has been found t hat the matrix elements of the axial-vector current dominate the K-14 decay s. PCAC is satisfied. A relationship between three form factors of the axia l-vector current has been predicted. Partial-wave analysis has been door. N on-zero phase shifts: are originated in rho --> pi pi. The decay rates are calculated in the chiral limit. In this study there is no adjustable parame ter.
