Description of the process $e^+ e^- \to \pi^0\pi^0 \gamma$ in the extended NJL model
About
The cross section of the process $e^+ e^- \to \pi^0\pi^0 \gamma$ is calculated in the extended NJL quark model. The vector channel with the intermediate $\rho$, $\omega$, $\rho'$ and $\omega'$ mesons is considered. The main contribution is given by the intermediate radially excited $\rho'$ meson. The role of the channel with the intermediate scalar meson is also discussed.
