TL;DR: The 5.8 pb −1 of data collected by the CMD-2 Collaboration in the energy range 1.05-1.38 GeV have been used to study energy dependence of the processes e + e − → π + π − 2 π 0 and e + ǫ − →2 π+ǫ +ǫǫ−ǫ 2 ρ + 2ǫ 0 as discussed by the authors, and upper limits for the contributions of other possible states are also obtained.
