Abstract

We have studied the ρ0 production rate in the reaction ξξ→3π+ in the energy range 1.6≦W γγ≦7.5 GeV with the CELLO detector at PETRA. Our analysis points to a substantial yield of ρ0ρ0π+π events in particular atW γγ>4.0 GeV. We give cross sections for the ρ0+ and ρ0ρ0π+π final states and calculate upper limits for the reaction γγ→ρ0ρ0 (1700) →ρ0ρ0π+π.
