Study of the process e+e-→ π+π-π0η at the SND detector

Abstract

The reaction e+e-→ π+π-π0η has been studied in the center-of-mass energy region below 2 GeV in the experiment with the SND detector at the VEPP-2000 e+e- collider. The reaction proceeds via the four intermediate states: ωη, ϕη$ \phi \eta $, a0(980)ρ, and a structureless π+π-π0η state, which may be, for example, ρ(1450)π state with ρ(1450) → ρ(770)η. The total e+e-→ π+π-π0η cross section and the cross section for its components, ωη, ϕη$ \phi \eta $, and a sum of a0(980)ρ and the structureless state, have been measured separately. Our results are in agreement with previous measurements and have comparable or better accuracies.
