Abstract :
Data on p̄p→ωπ0π0 from the Crystal Barrel experiment are presented in the range of beam momenta 600 to 1940 MeV/c. A partial wave analysis finds structures which may be interpreted in terms of a number of qq̄ resonances expected in this mass range. There is a well defined JPC=1+− resonance with mass and width M=2265±25 MeV, Γ=190±35 MeV, and a 3+− state with M=2275±35 MeV, Γ=180±35 MeV. There is a further well defined 1−− resonance with M=2145±20 MeV, Γ=200±25 making a natural I=0 partner for ρ(2150). In addition, there is evidence for a second, lower 1+− state and triplet 2−−, 1−− and 3−− states which are somewhat less well defined in masses and widths.
