Abstract
The cross sections for e+e- --> pi+pi-pi0 and e+e- --> omegapi+pi- have been measured in the 1.35 less-than-or-equal-to square-root s less-than-or-equal-to 2.4 GeV range from 1900 nb-1 collected by DM2 at DCI. The second process proceeds via a resonant state at congruent-to 1660 MeV/c2, congruent-to 280 MeV/c2 wide. The first one is larger than a VDM extrapolation from the omega-phi peaks and, although does not show any clear structure, is compatible with the presence of the above resonance.
