Abstract: (Elsevier)

In the study of e + e − annihilation into multihadrons, evidence is found for a resonant state around 1650 MeV/ c 2 in the π + π − π + π − π 0 and K S 0 K ± π ∓ channels. The π + π − π + π − channel shows the well known ϱ′(1600) signal with a significant a 1 π and ϱϵ dynamics while the π + π − π 0 π 0 , without ωπ 0 dynamics, shows a wide bump around 1650 MeV/ c 2 with a main ϱ ± π ∓ π 0 dynamics. Data have been collected with the DM2 detector at DCI, the Orsay colliding ring, and refer to about 2 pb −1 luminosity in the 1350–2400 MeV energy interval.
