“…If this apparent OZI violation is due to the presence of polarized strangeness in the nucleon, then it was predicted [15] that the φφ system should be produced mainly from the initial spin-triplet state. Recent data from the JETSET collaboration [48] indeed demonstrate that φφ production is dominated by the initial spin-triplet state with 2 ++ . Moreover, a preliminary analysis [50] shows that final states with total spin S = 2 for the φφ system are enhanced.…”

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.

“…The JETSET collaboration has seen an unusually high apparent violation of the OZI rule in the reactionp + p → φ + φ [48,49]. The measured cross section of this reaction turns out to be 2-4 µb for momenta of incoming antiprotons from 1.1 to 2.0 GeV/c.…”
