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

Conference ·
OSTI ID:5001937
A sensitive (greater than or equal to 5 events/nb) search for narrow anti pp states was carried out at the BNL Multiparticle Spectrometer. No evidence of narrow anti pp states was found at 2020 and 2200 MeV in the reaction ..pi../sup -/p ..-->.. p..pi../sup -/ anti pp at 16 GeV/c. 2 sigma upper limits of less than or equal to 3 nb are quoted for these states in the data. Based on the cross sections of the CERN ..cap omega.. experiment at 12 GeV/c and assuming baryon-exchange processes for the production, greater than or equal to 5 sigma signals should have been seen at 2020 and 2200 MeV.
