Search for exotic mesons produced by baryon exchange in the reaction pi /sup +/p to Lambda +x/sup ++/ at 12 GeV/c
A search for exotic mesons has been carried out at the CERN Omega spectrometer. The baryon-exchange reaction pi /sup +/p to Lambda +x /sup ++/ was studied at 12 GeV/c incident beam momentum. No evidence was found for the existence of doubly-charged strange mesons. The upper limit (95% confidence lev...

| description | A search for exotic mesons has been carried out at the CERN Omega spectrometer. The baryon-exchange reaction pi /sup +/p to Lambda +x /sup ++/ was studied at 12 GeV/c incident beam momentum. No evidence was found for the existence of doubly-charged strange mesons. The upper limit (95% confidence level) for this reaction is 60 nb for exotic mesons with squared masses from 1 to 7 (GeV/c/sup 2/)/sup 2/ and 150 nb for 7 to 13 (GeV/c/sup 2/)/sup 2/. These limits are of the same order of magnitude as the exotic cross-sections expected from two-component duality arguments. (10 refs). |
