摘要：

From a simultaneous analysis of data on ppBAR --> pi0pi0pi0 and ppBAR --> etaetapi0 at rest, two I = 0, J(PC) = 0++ resonances are identified above 1 GeV. The first has mass M = 1365(-20/-55) MeV and width GAMMA = 268 +/- 70 MeV, close to the f0 (1400) of the Particle Data Group. The second has M = 1520 +/- 25 mev, GAMMA = 148(+20/-25) MeV.
