Proton-antiproton annihilation into 6γ and 7γ Original Research Article

Preliminary results on ωπ0π0 and ωηπ0 in View the MathML source anihilation at rest [1] and on View the MathML source annihilation in flight into ηηπ0 [2] are briefly described. In ωηπ0 there is evidence for 1+− and 1−− mesons decaying to ωη. In ηηπ0 at 900 MeV/c the f0(1500) meson decaying into ηη is strongly produced, while the fJ(1710) is not observed.
