Аннотация

Using the SND detector, the process e+e- → π+π-π0 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 (Formula presented.) combinations were analyzed in the energy range between 1.15 and 2 GeV. This resulted in finding an indication that the (Formula presented.) excited state decayed predominantly through the (Formula presented.) intermediate state.
