Description
The decay J/Ψ → γ Φ Φ → γ K+ K- Ks0KL0 has been studied from 8 x 106 J/Ψ's produced in the DM2 apparatus at DCI. The branching ratio BR (J/Ψ → γ Φ Φ) = (3.4 ± 0.8 ± 0.6) x 10-4 agrees with the previous DM2 value from the four charged kaon mode. The analysis of both modes gives evidence of a resonant Φ Φ production around 2.24 GeV/c2, preferably pseudoscalar, which accounts for about one half of the total Φ Φ production below the ηc
