Data on pp → ηπ + π -π + π -at rest show two resonant processes: (a) f 0 (1370)η, f 0 (1370) → σ σ and ρρ, (b) η( 1440)σ , η(1440) → ηπ + π -. The branching ratio BR[f 0 (1370) → ρρ]/ BR[f 0 (1370) → σ σ ] = 0.98 ± 0.25 in the mass range available here. Using data on pp → ηπ 0 π 0 , the ratio Γ 4π /
