Description
Results of a partial-wave analysis for the reaction π-→ ωωn studied at the VES spectrometer (Institute for High Energy Physics, Protvino) are presented. The behavior of the JPC = 2++ amplitudes in the ωω system is described by the f2(1565) and f2(1910) resonances, whose parameters were fixed at M = 1.590 ± 0.010 GeV and Γ = 0.140 ± 0.011 GeV for the former and at M = 1.890 ± 0.010 GeV and Γ = 0.165 ± 0.019 GeV for the latter. The decay f4(2050) → ωω was observed at parameters values of M = 1.960 ± 0.015 GeV, Γ = 0.290 ± 0.020 GeV
