摘要: Abstract On the basis of a effective “superconductivity”-type four-quark interaction, phenomenological Lagrangians are obtained for interactions scalar, pseudoscalar, vector, and axial vector meson nonets. The include mass terms breaking chiral U (3) invariance corresponding to quark masses m u ≠ d s . It is shown that upon introducing boson fields current quarks in initial Lagrangian replaced by constituent Lagrangians. Estimates these presented. Electromagnetic considered, dominance model derived. widths various decays calculated.
