Abstract

In the experiment with the SND detector at VEPP-2M e^+e^- collider the process e+e−→π+π−π0e^+e^-\to\pi^+\pi^-\pi^0 was studied in the energy range 2E_0 from 1.04 to 1.38 GeV. A broad peak was observed with the visible mass Mvis=1220±20M_{vis}=1220\pm 20 MeV and cross section in the maximum σ0≃4\sigma_0\simeq 4 nb. The peak can be interpreted as a ω\omega-like resonance ω(1200)\omega (1200).
