abstract
In a single-arm magnetic spectrometer experiment at the CERN Intersecting Storage Rings (ISR), a prominent diffractive enhancement is observed for inclusive production of (p+-) systems near x 1 at s = 53 and 35 GeV. In testing limiting fragmentation and scaling for this system, inclusive p+- diffractive excitation into a fixed invariant mass range is found to possess a cross-section independent of s to within (3 5)%. The main component in the (p+-) system is (1236), with a charge structure compatible with the break-up of an isotopic spin 1 2 system. 1975.
