Abstract

An analysis of the recent data on J Ψ decays coming from the MARK III Collaboration is performed. It indicates that the J ψ → π+π-π0π0 decay proceeds through two constructively interfering ωπ0 and ρ{variant}0π0 intermediate states with a corrected BR(J/Ψ → ωπ0) ∼- (3.8 ± 0.5) × 10-4 and an anomalously large BR(ρ{variant}0 → π+π-π0) ∼- 10-2, not far from its experimental upper limit. © 1986.
