Inclusive Strange Particle Production in $\pi^+ p$ Interactions at 32-{GeV}/$c$

The production of K s 0 , Λ and Λ is measured in π + p interactions at 32 GeV/ c . The total inclusive cross sections are found to be 2.07±0.14, 1.00±0.10 and 0.14±0.04 mb, respectively. The energy dependence of total inclusive cross sections and inclusive distributions is discussed and a comparison is made with p, p , K + and K − induced reactions. We find that the factorization hypothesis is satisfied for the inclusive reactions π + p→ Λ X and K + p→ Λ X. Multi-strange-particle production is similar in π + p and K + p interactions at 32 GeV/ c . There is evidence for beam fragmentation in Λ production. The hierarchy of Λ inclusive cross sections in p , K + , π + and K − induced reactions at 32 GeV/ c is qualitatively explained by a quark recombination model. The cross sections for inclusive K ∗ + (892) and Σ + (1385) production in 32 GeV/ c π + p interactions are 1.07±0.57 mb and 0.19±0.08 mb, respectively.

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

The BRUSSELS-CERN-GENOA-MONS-NIJMEGEN-SERPUKHOV collaboration De Wolf, E.A. ; Johnson, D.P. ; Drevermann, H. ; et al.
Nucl.Phys.B 246 (1984) 431-461, 1984.
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.

Study of Elastic $\pi^+ p$, $K^+ p$ and $p p$ Scattering at 250-{GeV}/$c$

Inspire Record 246909 DOI 10.17182/hepdata.40833

Results are presented on π + p and K + p elastic scattering at 250 GeV/ c , the highest momentum so far reached for positive meson beams. The experiment (NA22) was performed with the european hybrid spectrometer. The π + p elastic cross section stays constant with energy while the K + p cross section increases.

Measurement of inclusive production of light meson resonances in hadronic decays of the Z0

The DELPHI collaboration Abreu, P. ; Adam, W. ; Adye, T. ; et al.
Phys.Lett.B 298 (1993) 236-246, 1993.
Inspire Record 342800 DOI 10.17182/hepdata.29001

A study of inclusive production of the meson resonances ρ 0 , K ∗0 (892), ƒ 0 (975) and ƒ 2 (1270) in hadronic decays of the Z 0 is presented. The measured mean meson multiplicity per hadronic event is 0.83 ± 0.14 for the ρ 0 0.64 ± 0.24 for the K ∗0 (892), 0.10 ± 0.04 for the ƒ 0 (975) in the momentum range p > 0.05 p beam ( x p > 0.05) and 0.11 ± 0.05 for the ƒ 2 (1270) for x p > 0.1 . These values and the corresponding differential cross sections ( 1 σ hadr ) d σ d x p for the vector mesons are in good agreement with the predictions of the JETSET 7.3 PS and HERWIG 5.4 models. The ƒ 2 (1270) production is overestimated by HERWIG but its x p -shape is correctly reproduced. The measured ratios of the production cross sections σ(ƒ 2 (1270)) σ(ρ 0 ) = 0.22 ± 0.08 and σ(ƒ 2 (1270)) σ(ƒ 0 (975)) = 3 −1 +7 for x p > 0.1 are consistent with the results obtained in hadronic reactions.
