Description
The cross sections for e+e-→π+π-π0 and e+e-→ωπ+π- have been measured in the 1.35≤√s≤2.4 GeV range from 1900 nb-1 collected by DM2 at DCI. The second process proceeds via a resonant state at ≅1660 MeV/c2, ≅280 MeV/c2 wide. The first one is larger than a VDM extrapolation from the ω-φ peaks and, although does not show any clear structure, is compatible with the presence of the above resonance. (orig.)
