Abstract :
Data on p̄p→ωηπ0 from the Crystal Barrel experiment are presented in the range of beam momenta 600 to 1940 MeV/c. A combined partial wave analysis of these data together with data on ωπ0 is reported. The ωηπ0 data require the presence of a JPC=3−− state with mass M=2265±20 MeV and width Γ=170±35 MeV and a JPC=2−− state with M=2240±55 MeV, Γ=330±60 MeV. They also require a 1+− state with M=2220±55 MeV, Γ=300±65 MeV. In the ωη mass spectrum, the ω1(1650) is observed with M=1664±17 MeV, Γ=260±40 MeV.
