Abstract

The ratio of the exclusive production cross sections for φ and ω mesons has been measured in ppreactions at Tbeam = 2.85 GeV. The observed φ/ω ratio is (3.7 ±0.7+1.2−0.9) × 10−3. After phase space corrections, this ratio is about a factor of 10 enhanced relative to naive predictions based upon the Okubo-Zweig-Iizuka rule, in comparison to an enhancement by a factor of ∼3 previously observed at higher energies. The modest increase of this enhancement near the production threshold is compared to the much larger increase of the φ/ω ratio observed in specific channels of p®p annihilation experiments.
