Processes $τ^{-} \to π^{-} π^{0} ν_{τ}$ and $e^{+} e^{-} \to π^{+} π^{-}$ in the chiral NJL model with final state interactions taken into account

M. K. Volkov, A. B. Arbuzov, A. A. Pivovarov

The processes $τ^{-} \to π^{-} π^{0} ν_{τ}$ and $e^{+} e^{-} \to π^{+} π^{-}$ are considered within the chiral Nambu--Jona-Lasinio model with taking into account the pion final state intera…

On the mixing angle of the vector mesons $ω (782)$ and $ϕ (1020)$

M. K. Volkov, A. A. Pivovarov, K. Nurlan

In the present work, the mixing angle of the vector $ω (782)$ and $ϕ (1020)$ mesons is estimated in the framework of Nambu--Jona-Lasinio model. The decay $ϕ \to π^{0} γ$ is considered…

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…
