High-statistics study of fo (1500) decay into °

A partial-wave analysis of the reaction p~--~zr°Tr°lr ° has been performed using a high-quality high-statistics data set of 712 000 events. In addition to the ]'0(975) and fo(1300), the scalar resonance with mass m = (1500-t- 15) MeV and width F = (120+ 25) MeV is necessary to describe the data.
