Abundant $\phi$-meson production in $\overline{p}$p annihilation at rest and strangeness in the nucleon

A large apparent violation of the OZI rule has recently been found in many channels in pbar-p annihilation LEAR. An interpretation of these data in terms of the "shake-out" and "rearrangement" of an intrinsic sbar-s component of the nucleon wave function is proposed. This gives a channel-dependent, non-universal modification of the naive OZI prediction. Within this approach, we interpret the strong excess of \phi production in S-wave pbar-p annihilations in terms of the polarization of the nucleon's sbar-s component indicated by deep inelastic lepton-nucleon scattering experiments. This interpretation could be tested by measurements of the f_2'(1525)/f_2(1270) production ratio in P-wave annihilations and by experiments with polarized beams and polarized targets. We also propose a test of the intrinsic strangeness hypothesis in \phi production in high-momentum transfer processes, via a difference in constituent counting rules from gluon-mediated production.
