Abstract
A partial wave analysis of the reaction pp->pi0etaeta has been performed, using a high quality, high statistics data set of 198,000 events. In addition to the f0(1370), a second scalar resonance decaying into etaeta, the f0(1500), with mass m = (1505 +/- 15) MeV and width Gamma = (120 +/- 30) MeV has to be introduced to describe the data.
