An extended C/(3)£® £/(3)/j chiral effective field theory which includes pseudoscalar and vector meson nonets as dynamic variables is presented. We combine the hidden symmetry approach with a general procedure of including the Tj' meson into chiral theory, and accounts for direct and indirect symmetry breaking effects via a mechanism based on the quark mass matrix. The theory is applied to anomalous radiative decays using particle mixing schemes, corresponding to different symmetry breaking assumptions and uniquely determined by the lagrangian presumed. Radiative decays of light flavor mesons are best explained within the framework of a one mixing angle scheme and provide evidence for SU(3)p and nonet symmetry breaking.
