Near threshold radiative 3$\pi$ production in $e^{+}{e}^{-}$ annihilation

A. Ahmedov, G. V. Fedotovich, E. A. Kuraev +1

We consider the ${\pi }^{+}{\pi }^{-}{\pi }_0\gamma$ final state in electron-positron annihilation at cms energies not far from the threshold. Both initial and final state radiations of the hard photon is…
