Abstract
We have previously interpreted the various large apparent violations of the naı̈ve Okubo–Zweig–Iizuka (OZI) rule found in many channels in p ̄ p annihilation at LEAR as evidence for an intrinsic polarized s ̄ s 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 the s ̄ s 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.
