Study of the Dynamics of the Process $${e}^{{+}}{e}^{{-}}{\to}{\pi}^{{+}}{\pi}^{{-}}{\pi}^{{0}}$$ in the Energy Range between 1.15 and 2.00 GeV

Using the SND detector, the process $$e^{+}e^{-}\to\pi^{+}\pi^{-}\pi^{0}$$ was studied in the energy range between 1.05 and 2.00 GeV. The respective measurement was performed on the basis of data accumulated in the experiments at the VEPP-2000 electron–positron collider throughout the runs of 2011 and 2012. Also, the invariant-mass spectra of the $$\pi^{+}\pi^{-}$$ and $$\pi^{\pm}\pi^{0}$$ combinations were analyzed in the energy range between 1.15 and 2 GeV. This resulted in finding an indication that the $$\omega(1680)$$ excited state decayed predominantly through the $$\rho^{\prime}\pi$$ intermediate state.
