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

The WA85 collaboration Abatzis, S. ; Andrighetto, A. ; Antinori, F. ; et al.
Phys.Lett.B 393 (1997) 210-216, 1997.
Inspire Record 456774 DOI 10.17182/hepdata.6511

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.

Hyperon production in proton sulphur collisions at 200-GeV/c.

The WA94 collaboration Abatzis, S ; Andersen, E ; Andrighetto, A ; et al.
Phys.Lett.B 400 (1997) 239-244, 1997.
Inspire Record 427129 DOI 10.17182/hepdata.12547

The WA94 experiment uses the production of strange particles and antiparticles to investigate the properties of hot hadronic matter created in heavy-ion interactions. Λ, Λ , Ξ − and Ξ + particle yields and transverse mass spectra are presented for pS interactions. These results are compared with those from SS interactions. Our results are also compared with those from pW and SW interactions of the WA85 experiment.

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

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.

Xi-, anti-xi-, Lambda and anti-Lambda production in sulphur - tungsten interactions at 200-GeV/c per nucleon

Multi-strange baryon and antibaryon 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, Λ' s , Λ ' s and Ξ − ' s produced in sulphur-tungsten interactions at 200 GeV/ c per nucleon and give the corrected rations Λ /Λ, Ξ − /Λ and Ξ − / Λ . Our ratio Ξ − / Λ appears to be larger than that from pp interactions.

Vector-meson electroproduction at high q-squared

Ahrens, L. ; Berkelman, Karl ; Brown, G.S. ; et al.
Phys.Rev.Lett. 31 (1973) 131-133, 1973.
Inspire Record 84487 DOI 10.17182/hepdata.47133

We have measured ρ0, ω (combined) and ϕ electroproduction over a range of virtual-photon four-momentum Q2 from 0.4 to 2.2 GeV2 and for photon energies ν from 2.7 to 8.6 GeV. We find that the slope of the t (momentum transfer) dependence of the ρ0 and ω forward peak decreases with increasing Q2 to less than half of the photoproduction slope.
