Abstract

In this article we print out preliminary results of an amplitude analysis of the e+e → 4π process. The amplitude analysis is performed using experimental data from the CMD-3 detector at the VEPP-2000 collider in the energy range 0.9-2.007 GeV. In the study the dominance of the e+e →ωπ0 →4π and e+e →a1(1260)π →4π amplitudes is proved, as well as sizable contributions of the ρ+ρ,ρ f0(980),ρσ and etc. states are observed. The obtained amplitude is used for the test of the isospin relations and hypothesis of conserved vector current (CVC).
