Results from\(\bar pp \to \phi \phi \)

The reaction\(\bar pp \to \phi \phi \) is investigated in the JETSET (PS202) experiment using an internal target in LEAR. Data have been analysed at a variety of beam momenta from 1.2 GeV/c to 2.0 GeV/c, corresponding to centre-of-mass energies between 2.15 GeV and 2.43 GeV. A strong φφ-signal was observed over the whole, energy range, preliminary results giving φφ-yields of (1–2) μb. No evidence for narrow resonances was found within the accumulated statistics. The capability of the experiment to measure φ→K+K− decay angular distributions and thus put constraints on the spin-parity quantum numbers of a possible resonant intermediate state is demonstrated.
