Abstract: (Elsevier)

The data of the CERN WA56 experiment that triggered the fast proton produced in the π + p and π − p interactions at beam momenta 20 GeV/c and 12 GeV/c, respectively, are used to analyse the final states pfΦ ( ω ) π ± . A large excess (up to two orders of magnitude) of the Φ ω cross sections ratio over the OZI prediction is observed.
