Résumé : We present our final data on the production of the baryonsp, Λ, Λ, Σ0, Σ0, 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-pT hadron-hadron collisions are examined and found to offer a reasonably successful description of the data. © 1984.
