A combined fit is presented to data on pbar-p annihilation in flight to final states eta-pizero-pizero, pizero-pizero, eta-eta, eta-etaprime and piminus-piplus. The emphasis lies in improving an earlier study of eta-pizero-pizero by fitting data at n

Data taken with the Crystal Barrel detector on p p → π 0 η , π 0 η ′ and 3 π 0 are presented at p momenta from 600 to 1940 MeV/c. We observe towers of I = 1 resonances up to J PC = 4 ++ at ∼ 2050 and ∼ 2300 MeV [1,2].

High statistics data on p p→ηπ 0 π 0 π 0 at nine beam momenta from 900 to 1940 MeV/c require the presence of three I=0, JPC=2−+ mesons with masses and widths (i) M=1645±6(stat)±20(syst) MeV, Γ=200±7±20 MeV, (ii) M=1860±5±15 MeV, Γ=250

New data on p p→ηπ 0 π 0 π 0 at beam momenta 900–1200 MeV/c reveal evidence for a threshold enhancement in the f0(980)η channel. Quantum numbers JPC=0−+ are preferred strongly over 1++ and 2−+. The enhancement may be interpreted as the h
