The OZI rule does not apply to baryons

Determinations of the π-N σ-term and the EMC measurement of deep inelastic polarized μp scattering and various theoretical arguments indicate that baryons contain a significant number of strange quark-antiquark pairs. Their presence gives rise to additional connected diagrams which evade the Okubo-Zweig-Iizuka (OZI) rule for meson-baryon couplings, and explain the apparent violation of the OZI rule in the reaction pp→φπ⁺π^- as well as the process pp→ppφ+pions, and the backward peak seen in pp→K⁺K^-. we catalogue predictions, based on moments of deep inelastic structure functions, for the OZI-evading couplings to baryons of 0^-+, 0⁺⁺, and 2⁺⁺ and other mesons. Processes where these predictions can be tested include backward meson production in π-N scattering as well as pp annihilation and pp scattering.
