Contribution of intermediate axial vector states to the $[\rho(770), \omega(782)] \to \gamma [\pi, \eta]$ electromagnetic decays in the Nambu–Jona-Lasinio model

The well-known $[\rho(770), \omega(782)] \to \gamma [\pi, \eta]$ electromagnetic decays have been considered within the Nambu-Jona-Lasinio model taking into account contributions from intermediate transitions between axial-vector and pseudoscalar vertices using the $[f_{1}(1285), a_{1}(1260)] \to \gamma [\rho(770), \omega(782)]$ vertices recently obtained within this model. The results are in satisfactory agreement with experimental data.
