Energy, charge and strangeness flow inK+p interactions at 32 and 70 GeV/c, and π+p interactions at 32 GeV/c are studied in terms of the angular variable λ=|x|/pT. The data ondQ/dλ anddE/dλ show only a weak indication of scale breaking between 32 and 70 GeV/c. For inclusive “non-diffractive”, inclusive “diffractive” and exclusive “non-diffractive” jets, the fraction of charge in any angular region ΔΩ away from the central region is found to be proportional to the energy fraction in the same interval. The data ondQ/dE versus λ are compatible with some versions of dual-sheet models and agree also with the LUND Monte-Carlo model. The data are also compared with\(v(\bar v)p\) interactions in BEBC. In exclusive channels the average ratiodQ/dS=0.78±0.04 is consistent, in the framework of fragmentation models, with a larger probability for the fragmentation of the\(\bar s\)-valence quark than theu-valence quark in theK+-meson.

INCLUSIVE BARYON PRODUCTION IN K+ P INTERACTIONS AT 70-GeV/c

Inspire Record 209444 DOI 10.17182/hepdata.33847

We present our final data on the production of the baryons p, Λ, Λ , Σ 0 , Σ 0 , Σ − , Σ + , Ω + , and of the baryon resonances Δ ++ (1232), Σ ∗± (1385), Σ ∗± (1385) in K + p interactions at 70 GeV/ c . Results are given on total and semi-inclusive cross sections, transverse momentum distributions and Feynman- x spectra. The data are compared with measurements at 32 GeV/ c and other energies. The predictions of the LUND fragmentation model for low- p T hadron-hadron collisions are examined and found to offer a reasonably successful description of the data.

In an exposure of the chamber Mirabelle at the Serpukhov accelerator, 1 943 interactions at 50 GeV/ c and 8 959 at 69 GeV/ c have been observed. Topological cross sections and charged multiplicity distributions are presented. The average charged multiplicities found are respectively 5.32 ± 0.13 and 5.89 ± 0.07.

Inclusive $\phi$ Production in $K^+ p$ Interactions at 70-{GeV}/$c$

We present results on inclusive φ meson production in K + p interactions at 70 GeV/ c in the kaon fragmentation x >0.2 region. Comparison with other data on φ meson production in K ± and p induced reactions provides evidence that the strange valence-quark fragmentation or recombination processes play the dominant role in the K ± → φ transitions. Arguments are presented that the kaon valence strange s -quark carries a much higher momentum fraction than the u-quark. Evidence for the previously observed narrow φπ + state at mass ∼2.1 GeV is discussed.

Phys.Lett.B 121 (1983) 183, 1983.
Inspire Record 179546 DOI 10.17182/hepdata.41221

We present results on the inclusive polarization of Λ hyperons produced in K + p interactions at 32 and 70 GeV/ c . A large positive Λ polarization is observed in the kaon fragmentation region. The polarization is energy independent, increases strongly with increasing x , but shows essentially no p T -dependence.
