On the basis of a effective "superconductivity"-type four-quark interaction, phenomenological Lagrangians are obtained for interactions of scalar, pseudoscalar, vector. and axial vector meson nonets. The Lagrangians include mass terms breaking chiral and U(3) invariance and corresponding to the quar
Phenomenological aspects of SU(3)-breaking in VPP, PPy, VPy and Pyy vertices involving pseudoscalar-mesons (P), vector-mesons (V) and photons are discussed in the framework of a generic constituent-quark model. A rather satisfactory description is achieved adding some relevance to this type of model
