摘要：

An experiment has been undertaken at the CERN SPS, using the Omega spectrometer, aimed at confirming the enhancement observed in a ppφ- mass spectrum at 2.95 GeV [1]. With statistics of twelve times the original experiment no signal is seen. In the reaction φ-p→ppφ-p, the upper limit (four standard deviations) for the production of a resonance in the ppφ- system at 2.95 GeV, with a width ≤ 30 MeV, is 50 nb. © 1979.
