| Abstract | This Letter carries out a sensitive ( approximately 5 events/nb) search for narrow pp states at the Brookhaven National Laboratory multiparticle spectrometer. No evidence is found for such states in the mass range 1900-2400 MeV/c/sup 2/ in the reaction pi /sup -/p to p pi /sup -/pp at 16 GeV/c. In particular, the pp states at 2020 and 2200 MeV/c/sup 2/ previously reported in a CERN Omega -spectrometer experiment are not observed. (7 refs). |
