“…Analogous differences in the angular distributions of φ and ω mesons produced in pp → ppφ(ω) interactions were observed by the DISTO collaboration [33]. Whereas the φ meson was found to be formed predominantly in an S-wave state relative to the pp system, the ω angular distribution reveals contributions from higher partial waves.…”

Hadronic probes of the polarized intrinsic strangeness of the nucleon

We have previously interpreted the various large apparent violations of the naïve Okubo-Zweig-Iizuka (OZI) rule found in many channels inpp annihilation at LEAR as evidence for an intrinsic polarized ss component of the nucleon wave function. The model is further supported by new data from LEAR and elsewhere. Here we discuss in more detail the possible form of thess component of the nucleon wave function, interpret the new data and clarify the relative roles of strangeness shake-out and rearrangement, discuss whether alternative interpretations are still allowed by the new data, and propose more tests of the model.

“…In this context we shall show that the angular distribution of the produced φ-mesons plays a crucial role. In particular, we will demonstrate that the almost isotropic angular distribution seen in the data from the DISTO collaboration [6] indicates that the NNφ coupling is very small. In the absence of a set of data sufficient to permit an accurate determination of the NNφ coupling strength, we impose certain reasonable assumptions and carry out a combined analysis of the recent φ-meson production data of the DISTO collaboration [6] and the data of ω-meson production from SATURNE [27].…”

“…Of course, there is also an alternative picture: one in which the coupling of the should provide a clear sign for a possible OZI violation. Indeed, data presented recently by the DISTO collaboration [6] indicate that this ratio, after correcting for the phase space effects, is about eight times larger than the OZI estimate (1).…”

“…The investigation of φ-meson production in both hadronic [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] and electromagnetic [16,17] processes at low and intermediate energies has attracted much attention in recent years. A major motivation for those studies is the hope that one can obtain information about the amount of hidden strangeness in the nucleon.…”

φ-meson production in proton-proton collisions

et al. 1999

The production of φ-mesons in proton-proton collisions is investigated within a relativistic meson-exchange model of hadronic interactions. The experimental prerequisites for extracting the N N φ coupling strength from this reaction are discussed. In the absence of a sufficient set of data, which would enable an accurate determination of the N N φ coupling strength, we perform a combined analysis, based on some reasonable assumptions, of the existing data for both ω-and φ-meson production. We find that the recent data from the DISTO collaboration on the angular distribution of the φ meson indicate that the N N φ coupling constant is small. The analysis yields values for g N N φ that are compatible with the OZI rule.
