Abstract

The production of phi mesons in proton-proton collisions is investigated within a relativistic meson-exchange model of hadronic interactions. The experimental prerequisites for extracting the NN phi coupling strength from this reaction are discussed. In the absence of a sufficient set of data, which would enable an accurate determination of the NN phi coupling strength, we perform a combined analysis, based on some reasonable assumptions, of theexisting data for both omega- and phi-meson production. We find that the recent data from the DISTO Collaboration on the angular distribution of the phi meson indicate that the NN phi coupling constant is small. The analysisyields values for g(NN phi) that are compatible with the Okubo-Zweig-Iizuka rule. [S0556-2813(99)00611-1].
