Processes $e^{+}{e}^{-}\to {\pi }^0({{\pi }^0}^{\prime })\gamma$ in the NJL model

A. B. Arbuzov, E. A. Kuraev, M. K. Volkov

The processes of electron-positron annihilation into ${\pi }^0\gamma$ and into ${\pi }^{\prime }(1300)\gamma$ are considered within the NJL model. Intermediate vector mesons ${\rho }^0$, $\omega$, ${\rho }^{\prime }(1450)$, and $ω'(142…
