Abstract
The result of the partial wave analysis of Crystal Barrel data on pp → π 0π 0,ηη and ηη′ combined with earlier data on dσ dΩ and polarization for pp → π −π + is presented. The polarization data separate cleanly states with L = J ± 1, while Crystal Barrel data provide possibility to define quark content of the observed resonances. Along with other states, four I = 0, J PC = 2 ++ resonances are identified. All 2 + resonances have flavour composition close to n n = ( u u + d d )/ 2 , with rather little s s component. The possible nonet classification of the found states is discussed.
