An analysis of the Λ p p system produced forward in the reaction K p → Λ p p at 18.5 GeV/ c is presented. The data come from an experiment using the CERN Ω′ spectrometer. Structures are observed in the Λ p mass spectrum and in the double moments H LMlm describing the decay of the Λ p system and the subsequent Λ decay, for L ⩽ 8. A partial wave analysis interprets these structures as resonances of spin parities 2 − and 3 + , masses and widths M = 2200 ± 40 MeV, Γ = 150 ± 30 MeV and M = 2330 ± 40 MeV, Γ = 150 ± 30 MeV respectively.

Results from the first PWA of the K + K − system produced by incident K − , are presented in the mass range from the threshold to 1.70 GeV. In the P and D waves only the φ and f′ mesons are observed and their production mechanism studied. A broad S wave peaking at 1.4 GeV is observed but the lack of information about its phase makes the search for new 0 ++ mesons inconclusive.

A Partial Wave Analysis of the $K^- \phi$ System Produced in the Reaction $K^- p \to K^+ K^- K^- p$ at 18.5-{GeV}/$c$

The Bari-Birmingham-CERN-Milan-Paris-Pavia collaboration Armstrong, T. ; Baubillier, M. ; Beusch, W. ; et al.
Nucl.Phys.B 221 (1983) 1-15, 1983.

About 15 000 K − Φp events have been collected in the CERN Ω′ spectrometer. A partial-wave decomposition of the K − Φ system is performed. The 1 + SO + wave is dominant. The 0 − P0 + and 2 − P0 + waves are important and show resonant behaviour at ∼ 1.83 GeV (Γ ∼ 0.25 GeV) and ∼ 1.73 GeV (Γ ∼ 0.22 GeV) respectively. The first one can be interpreted as the second radial excitation of the kaon while the second one can be identified as one of the two L mesons.

SEARCH FOR NONSTRANGE BARYONIUM STATES IN THE BARYON EXCHANGE REACTION K- P ---> Y0 ANTI-P P AT 18.5-GeV/c

Narrow baryonium production in the baryon exchange reactions K − p → Λ p p and K − p → pK − p p at 18.5 GeV/ c is investigated in a 12 events/nb experiment performed at the CERN Ω′ spectrometer. No narrow structure is observed in the p p mass spectra. Upper limits for production of baryonium states are given as a function of p p mass.

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

Inspire Record 500180 DOI 10.17182/hepdata.28123

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.

Evidence for Structure in the 1.7-{GeV} Mass Region of the $K^+ K^-$ Final State Centrally Produced in the Reactions $\pi^+ p \to \pi^+ (K^+ K^-$) $p$ and $p p \to p (K^+ K^-$) $p$ at 85-{GeV}/$c$

The reactions π + p → π + (K + K − )p and pp → p(K + K − )p where the K + K − system is centrally produced have been studied at 85 GeV/ c . The K + K − spectrum contains several structures in the regions of S ∗ ø , f A 2 and f′. Structure is observed in the 1.7 GeV mass region which cannot be attributed to the g meson. The most likely interpretation of the data is that we observe the θ with a mass of 1.742 GeV and a new resonance at a mass of 1.629±0.010 GeV with a width of 0.082±0.030 GeV.

The reactions π + p → π + ( K + K + K − K − ) p and pp → p ( K + K + K − K − ) p in which the K + K + K − K − system is centrally produced have been studied at 85 GeV c . Evidence is found for φφ production. The relative rates for production of φφ , φK + K − and K + K + K − K − have been determined.
