Enhancement of strange and multi-strange baryons and anti-baryons in S W interactions at 200-GeV/c.

Strange and multistrange baryon production is expected to be enhanced in heavy ion interactions if a phase transition from hadronic matter to a Quark-Gluon Plasma takes place. The production yields of Λ s, Λ s, Ξ − s, and Ξ + s relative to the production of negative particles are presented for sulphur-tungsten interactions at 200 GeV/ c per nucleon. These production yields are compared to those produced in proton-tungsten interactions and the enhancements of strange and multistrange baryons and antibaryons are presented.

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.

Measurement of the Omega / Xi production ratio in central S - W interactions at 200-A-GeV/c

The WA85 collaboration Abatzis, S. ; Andrighetto, A. ; Antinori, F. ; et al.
Phys.Lett.B 347 (1995) 158-160, 1995.
Inspire Record 402400 DOI 10.17182/hepdata.27095

Strange baryon and in particular multi-strange baryon production is suggested to be a useful probe in the search for quark gluon plasma formation in heavy ion collisions. We have measured the (Ω − + Ω + ) (Ξ − + Ξ + ) production ratio to be 0.8±0.4 at central rapidity and ϱ T > 1.6 GeV/c.

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.
Nucl.Phys.A 544 (1992) 321-334, 1992.
Inspire Record 321220 DOI 10.17182/hepdata.36664

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.
