Hyperon production in proton tungsten interactions at 200-GeV/c

The WA85 collaboration Abatzis, S. ; Andrighetto, A. ; Antinori, F. ; et al.

The relative production yields and transverse mass spectra for Λ, Λ , Ξ − and Ξ + hyperons in proton-tungsten interactions are presented and compared with the WA85 results from central sulphur-tungsten interactions. A study of the negative particle yield has also been undertaken and the ratio of Λ hyperons to negative particles has been calculated.

Strange particle production in sulphur - tungsten interactions at 200-GeV/c per nucleon

The WA85 collaboration Kinson, J.B. ; Abatzis, S. ; Antinori, F. ; et al.

Multi-strange baryon and anti-baryon production is expected to be a useful probe in the search for Quark-Gluon Plasma formation. We present the transverse mass distributions of negative particles, K o s, Λs, Λ s, and Ξ − s produced in sulphurtungsten interactions at 200 GeV/c per nucleon and give the corrected ratios Λ Λ, Ξ − Λ and Ξ − /Λ . We note that our ratio Ξ − / Λ appears large in comparison to that from p p interactions.
