We present inclusive ¶ and K *0 (892) cross sections and Feynman x -spectra in K + p collisions at 250 GeV/ c . In the K + fragmentation region, x > 0.2, the ratio of ¶ to K *0 (892) is used to estimate the strangeness suppression factor λ , with the result γ =0.17 ± 0.02 (stat ± 0.01 (syst). We see no evidence for an energy dependence of λ in the CM energy range 7.8 ≤ s ≤21.7 GeV.

Inclusive $K^$+ (890), $K^$+ (1430) and $\bar{K}^*$ (890) Production in $K^+ p$ Interactions at 32-{GeV}/$c$

Azhinenko, I.V. ; Belokopytov, Yu.A. ; Borovikov, A.A. ; et al.

Z.Phys.C 25 (1984) 103, 1984.

Inspire Record 195755 DOI 10.17182/hepdata.47703

We present final results on inclusive production ofK*+(890),K*+(1430) andK*−(890) in$\bar K^ +p$ interactions at 32 GeV/c, based on a statistics of ∼27 events/μb. Total cross sections,pT-andx-dependence of inclusive distributions are compared with experiments at other energies and with the Lund fragmentation model. Spin density matrix elements of theK*+(890) are also discussed. The results suggest that “recombination” of both initial state valence quarks$\bar s$ andu of theK+ intoK*+(890), responsible in the Lund model for ∼45% of theK*+(890) cross section, is strongly suppressed.

Neutral Strange Particle Production in $K^+ p$ Interactions

The CERN-Soviet collaboration Ajinenko, I.V. ; Chliapnikov, P.V. ; Falaleev, V.P. ; et al.

Z.Phys.C 23 (1984) 307, 1984.

Inspire Record 193424 DOI 10.17182/hepdata.10722

The production properties ofKs0,$\bar \Lambda$ andK+p interactions at 32 GeV/c are investigated using the final statistics of the experiment. We present total and semi-inclusive cross sections and aver-age multiplicities. Estimates are given of the diffractive dissociation contributions to total and differential cross sections. Thex-,pT−, and transverse mass dependence of inclusive and semi-inclusive distributions is discussed as well as properties of “prompt”Ks0's. The ratio of “prompt”K890+ (K8900) to “prompt”K0 cross sections is measured to be 1.03±0.12 (0.98±0.17). From a comparison of$\bar \Lambda$ production inK±p interactions at 32 GeV/c, we estimate a strange sea-quark suppression of 0.26 ±0.02. The double differential cross sections ofKs0's is studied as a function of Feynman-x andpT2, and a Triple-Regge fit performed. The data are compared in detail to versions of the Lund-model for low-pT hadronic collisions.
