Abstract
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.
