The cross sections for e e→ π π π and e e→ ωπ π have been measured in the 1.35 ≦ $$\sqrt s $$ ≦2.4 GeV range from 1900 nb collected by DM2 at DCI. The second process proceeds via a resonant state at ≈- 1660 MeV/c, ≈- 280 MeV/c 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. [ABSTRACT FROM AUTHOR] |
