Abstract: (Springer)
We have studied the ρ0 production rate in the reaction ξξ→3π+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 atWγγ>4.0 GeV. We give cross sections for the ρ02π+2π− and ρ0ρ0π+π− final states and calculate upper limits for the reaction γγ→ρ0ρ0 (1700) →ρ0ρ0π+π−.
