Abstract

The well-known [ρ(770), ω(782)] → γ[π, η] 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 [f1(1285), a1(1260)] → γ[ρ(770), ω(782)] vertices recently obtained within this model. The results are in satisfactory agreement with experimental data.
