Abstract
We have studied backward baryon and meson production in at 8.0 GeV/c using a streamer chamber triggered by the detection of a fast forward proton. Our data sample (1227 events) displays prominent and quasi-two-body production. These states are investigated with regard to the peripheral nature of the production mechanism and sequential decay of the excited baryon and meson systems. The quasi-two-body production of and intermediate states is consistent with -channel proton exchange as the dominant production mechanism. In the mass distribution we observe a 3- to 4- standard-deviation enhancement at MeV/ with full width at half maximum = 110 ± 82 MeV/, but find no but find no evidence for backward or production. We observe production in the effective mass distribution.
