Okubo-Zweig-Iizuka rule violation in the reaction pp → f′2π0

The interpretation of the OZI-rule violation in the reaction pp → Φπ0 encounters difficulties since one cannot exclude the possibility that the violation is a consequence of the rescattering in the final state. For this reason it is important to seek reactions in which the OZI-rule violation cannot be explained by conventional mechanisms. We compute the rescattering contribution in the reaction pp → f′2π0 and show that this contribution is negligible. Therefore any substantial OZI-rule violation in the process pp → f′2π0 would undoubtedly mean that some unusual physics plays an important role in this process.
