Resonances formed by pp and decaying into π0π0η for masses 1960 t0 2410 MeV Original Research Article

Data on View the MathML source annihilation in flight into π0π0η are presented for nine beam momenta 600 t0 1940 MeV/c. The strongest four intermediate states are found to be f2(1270)η, a2(1320)π, ση and a0(980)π. Partial wave analysis is performed mainly to look for resonances formed by View the MathML source and decaying into π0π0η through these intermediate states. There is evidence for the following s-channelI = 0 resonances: two 4++ resonances with mass and width (M, Γ) at (2044, 208) MeV and (2320±30, 220±30) MeV; three 2++ resonances at (2020±50, 200±70) MeV, (2240±40, 170±50) MeV and (2370±50, 320±50) MeV; two 3++ resonances at (2000±40, 250±40) MeV and (2280±30, 210±30) MeV; a 1++ resonance at (2340±40, 340±40) MeV; and two 2−+ resonances at (2040±40, 190±40) MeV and (2300±40, 270±40) MeV.
