Decay widths of radially excited vector mesons of the $U (3)$ nonet with production of three pseudoscalar mesons in the extended NJL model

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

In the extended NJL model, the decays of the first radially excited vector mesons $ρ^{'}$ , $ω^{'}$ , $ϕ^{'}$ and $K^{*}^{'}$ with production of $3 P$ , where $P = K, π, η$ are calculated. The box chan…

Description of the process $e^{+} e^{-} \to π^{0} π^{0} γ$ in the extended NJL model

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

The cross section of the process $e^{+} e^{-} \to π^{0} π^{0} γ$ is calculated in the extended NJL quark model. The vector channel with the intermediate $ρ$ , $ω$ , $ρ^{'}$ and $ω^{'}$ mesons is co…

Two-body decays of radially excited $η (1295)$ and $η (1475)$ mesons in the extended NJL model

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

In the extended NJL model, two-body strong decays of the radially excited $η (1295)$ and $η (1475)$ mesons are described. It is shown that the two-body decays $η(1475)\to K_0^*K, a_0…

Chiral anomaly in the $η^{(')} \to π^{+} π^{-} γ$ and $η^{(')} \to π^{+} π^{-} l^{+} l^{-}$ decays

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

We report the presence of a flavor-violating correction to the $V AAA$ -type anomaly, $δ^{(')}$ , induced by the surface terms of the anomalous quark triangle diagram, previously…
