Description
My talk is about an analysis of the process $e^+e^- \to 4 \pi$ with the CMD-3 detector at the VEPP-2000 Collider in the energy range 0.9--2.007 GeV. In my contribution I will focus on the study of the intermediate dynamics of the reaction, i.e. I will talk about the results in the distinguishing of different intermediate mechanisms. The dominance of the (omega pi0) and (a1 pi) amplitudes will be proved. as well as the contribution of the rho+rho-, rho f0. rho sigma and etc. states will be discussed. Also, I will demonstrate the test of the isospin relation between the processes e+e- \to pi+ pi- 2pi0
