This approach is based on the linear sigma-model extended by the gauge and quark-meson interactions. Physical content and parameters of the model are discussed. Theoretical predictions for some radiative decays of vector mesons are in a good agreement with the experimental data.16 pages, 4 figures, change content, added referencesHigh Energy Physics - Phenomenologytext
