Description
A study has been performed of the reaction p̅ p⃗4K± using in-flight antiprotons from 1.1 to 2.0 GeV/c incident momentum interacting with a hydrogen jet target. The reaction is dominated by the production of a pair of φ mesons. The p̅ p⃗φφ cross section rises sharply above threshold and then falls continuously as a function of increasing antiproton momentum. The overall magnitude of the cross section exceeds expectations from a simple application of the Okubo-Zweig-Iizuka rule by two orders of magnitude. In a fine scan around the ξ/fJ(2230) resonance, no structure is observed. A limit is set for the double branching ratio B(ξ⃗p̅ p)×B(ξ⃗φφ)<6×10-5 for a spin 2 resonance of M=2.235 GeV and Γ=15MeV.
