Abstract
The cross section of the process e+e−→3(π+π−)π0 has been measured for the first time using a data sample of 56.7 pb−1 collected with the CMD-3 detector at the VEPP-2000 e+e− collider. 632±32 signal events have been selected in the center-of-mass energy range 1.6–2.0 GeV. A study of dynamics of seven-pion production allows one to extract contributions of the dominated 2(π+π−)ω and 2(π+π−)η intermediate states.
