Account for axial vector mesons in the $η \to π^{+} π^{-} γ$ and $η^{'} \to π^{+} π^{-} γ$ decays

A. A. Osipov, A. A. Pivovarov, M. K. Volkov +1

The rates and spectra of the anomalous $η \to π^{+} π^{-} γ$ and $η^{'} \to π^{+} π^{-} γ$ decays are calculated. The approach is based on the effective meson Lagrangian obtained in the Nambu-Jona-L…

Low-energy theorem for $γ \to 3 π$ : surface terms against $π a_{1}$ -mixing

A. A. Osipov, M. M. Khalifa, B. Hiller

We reconsider the contribution due to $π a_{1}$ -mixing to the anomalous $γ \to π^{+} π^{0} π^{-}$ amplitude from the standpoint of the low-energy theorem $F^{π} = e f_{π}^{2} F^{3 π}$ , which relates the…
