rivet Analysis
$\eta$ and $\eta^\prime$ Production in $e^+ e^-$ Annihilation at 29-{GeV}: Indications for the $D(s$)+- Decays Into $\eta \pi^\pm$ and $\eta^\prime \pi^\pm$

η production has been investigated by the Mark II collaboration at the SLAC e+e− storage ring PEP. η particles are reconstructed by their γγ decay mode. The η fragmentation function has been measured and found to be in good agreement with the Lund-model prediction. η′ production has been measured for the first time in high-energy e+e− annihilation. There is evidence at the 3σ level for Ds± decay into ηπ± and η′π±.

Neutral Strange Particle Productions and Inelastic Cross-section in $\bar{p}$ Ta Reaction at 4-{GeV}/$c$

Miyano, K. ; Noguchi, Y. ; Yoshimura, Y. ; et al.
Phys.Rev.C 38 (1988) 2788-2798, 1988.
Inspire Record 261403 DOI 10.17182/hepdata.26211

The inclusive production of Ks0, Λ, Λ¯, and Ks0Λ in the p¯Ta reaction at 4 GeV/c was measured and compared with that in the p¯p reaction. The total inelastic and topological cross sections were also measured. The number of Λ’s produced in the p¯Ta reaction was 11.3 times larger than that expected from the geometrical cross section, which is defined as A2/3 times the cross section for the p¯p reaction. The yield ratio Λ¯/Λ was found to be 2×10−2. These values cannot be accounted for by a straightforward extension of the p¯N reaction. Besides, a correlation of 2 vees like Ks0-Λ could not prove their simultaneous production. Nuclear temperatures of 135 and 97 MeV were obtained from the kinetic energy spectra of Ks0 and Λ, respectively. The kinematical characteristics of the Ks0 and Λ produced were analyzed in terms of the fireball model.

Central Collisions of 14.6-{GeV}/nucleon, 60-{GeV}/nucleon, and 200-{GeV}/nucleon $^{16}$O Nuclei in Nuclear Emulsion

Barbier, L.M. ; Freier, P.S. ; Holynski, R. ; et al.
Phys.Rev.Lett. 60 (1988) 405-407, 1988.
Inspire Record 264260 DOI 10.17182/hepdata.2969

Central collisions of O16 nuclei with the Ag107 and Br80 nuclei in nuclear emulsion at 14.6, 60, and 200 GeV/nucleon are compared with proton-emulsion data at equivalent energies. The multiplicities of produced charged secondaries are consistent with the predictions of superposition models. At 200 GeV/nucleon the central particle pseudorapidity density is 58±2 for those events with multiplicities exceeding 200 particles.

Charged Particle Multiplicities and Interaction Cross-sections in High-energy Nuclear Collisions

The NA35 collaboration Bamberger, A. ; Bangert, D. ; Bartke, J. ; et al.
Phys.Lett.B 205 (1988) 583-589, 1988.
Inspire Record 262284 DOI 10.17182/hepdata.42035

Inelastic cross sections at 60 and 200 GeV/nucleon are determined in a streamer chamber for 16 O on several nuclear targets. Charged particle multiplicity distributions for inelastic and central collisions are studied and compared with theoretical predictions. The inelastic cross section exhibit a geometrical dependence on nuclear radii. The multiplicity data are governed by the collision geometry. They are consistent with a picture of superposition of independent nucleon-nucleus interactions.

Correlations Among Particles Produced in Proton Interactions With Emulsion Nuclei at 800-{GeV}

Barbier, L.M. ; Jones, W.V. ; Wefel, J.P. ; et al.
Phys.Rev.D 37 (1988) 1113, 1988.
Inspire Record 256580 DOI 10.17182/hepdata.3823

Correlations among the produced particles in interactions of 800-GeV protons with nuclei in photographic emulsion provide evidence for nonindependent production of the secondary particles. Assuming particle production in clusters, the analysis implies an average multiplicity of about 3 charged particles per cluster.
