摘要：

A sample of 80 000 events in the reaction π+p → (π+pp̄)p has been obtained at 50 GeV/c at the CERN SPS with the Geneva-Lausanne spectrometer. Upper limits on the cross section for diffractive production of narrow πpp̄ and pp̄ states are given in the mass ranges 2.2 ≤ Mπp p ̄ ≤ 4 GeV and 1.88 ≤ Mp p ̄ ≤ 2.7 GeV. © 1979.
