Abstract

The exclusive production cross sections for ω and φ mesons have been measured in proton-proton reactions at p_lab=3.67 GeV/c. The observed φ/ω cross section ratio is (3.8±0.2^+1.2_-0.9)× 10^-3. After phase space corrections, this ratio is enhanced by about an order of magnitude relative to naive predictions based upon the Okubo-Zweig-Iizuka (OZI) rule, in comparison to an enhancement by a factor ∼3 previously observed at higher beam momenta. 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 p̄p annihilation experiments. Furthermore, differential cross section results are also presented which indicate that although the φ meson is predominantly produced from a ³P₁ proton-proton entrance channel, other partial waves contribute significantly to the production mechanism at this beam momentum.
