Abstract

The exclusive production cross sections for [Formula Presented] and [Formula Presented] mesons have been measured in proton-proton reactions at [Formula Presented] The observed [Formula Presented] cross section ratio is [Formula Presented] 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 [Formula Presented] 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 [Formula Presented] ratio observed in specific channels of [Formula Presented] annihilation experiments. Furthermore, differential cross section results are also presented which indicate that although the [Formula Presented] meson is predominantly produced from a [Formula Presented] proton-proton entrance channel, other partial waves contribute significantly to the production mechanism at this beam momentum.
