Search for narrow p states in the reaction pi /sup -/p to p pi /sup - /pp at 16 GeV/c

The authors have carried out a sensitive (>or approximately=5 events /nb) search for narrow pp states at the BNL Multiparticle Spectrometer. They found no evidence of narrow pp states at 2020 and 2200 MeV in the reaction pi /sup -/p to p pi /sup -/pp at 16 GeV/c. The authors quote 2 sigma upper l...

description The authors have carried out a sensitive (>or approximately=5 events /nb) search for narrow pp states at the BNL Multiparticle Spectrometer. They found no evidence of narrow pp states at 2020 and 2200 MeV in the reaction pi /sup -/p to p pi /sup -/pp at 16 GeV/c. The authors quote 2 sigma upper limits of <or approximately=3 nb for these states in their data. Based on the cross sections of the CERN Omega experiment at 12 GeV/c and assuming baryon-exchange processes for the production, they should have seen >or approximately=5 sigma signals at 2020 and 2200 MeV. (5 refs).
