The process e+e-→ π+π-π0 in the enemy range 2E0= 1.04-1.38 GeV
In the experiment with the SND detector at VEPP-2M e+e- collider the process e+e-→ π+π-π0was studied in the energy range 2E0 from 1.04 to 1.38 GeV. A broad peak was observed with the visible mass Mvis = 1220 ± 20 MeV and cross section in the maximum σ0 ≃ 4 nb. The peak can be interpreted as a ω-like resonance ω(120). © 1999 Published by Elsevier Science B.V. All rights reserved.
