Abstract

We have studied the ρ0 production rate in the reaction ξξ→3π+- in the energy range 1.6≦Wγγ≦7.5 GeV with the CELLO detector at PETRA. Our analysis points to a substantial yield of ρ0ρ0π+π- events in particular at Wγγ>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-.
