VACUUM-STRUCTURE, CHIRAL-SYMMETRY BREAKING AND RADIATIVE DECAYS OF VECTOR-MESONS

The radiative decay widths of vector mesons were considered in a model involving chiral symmetry breaking through a nontrivial vacuum struct ure where the pion and kaon being treated consistently yield the const ituent quark wave functions, approximately the same as that obtained f rom the gap equations and thus in a way determine the constituent quar k field operators. Like its earlier success to some low energy hadroni c phenomena. here also the model calculations of radiative decay width s of mesons are in reasonable agreements with other theoretical estima tions as well as experimental measurements.
