EXISTENCE OF XI RESONANCES ABOVE 2-GEV

Ξ*− production was studied in the reaction K−+p→K+slow+X− at 5 GeV/c. The slow K+ was electronically detected, while the X− was observed as a missing mass, thus allowing for observation of all Ξ* independent of decay mode. The observed Ξ states were Ξ(1320), Ξ(1530), Ξ(1820), Ξ(2030), Ξ(2250), Ξ(2370), and Ξ(2500). These data establish and confirm the existence of Ξ(2250) and indicate a peculiar production-cross-section behavior for the Ξ*(2370).

We present new data for the reaction K−p→Ξ−K+ at 3.9-, 4.6-, and 5.0-GeV/c incident momenta. We compare the behavior of K−p→Ξ−K+ with K+p→pK+ backward scattering using a simple model with Reggeized baryon exchange and SU(3).
