Inclusive production cross sections have been measured for the processes p+A→Ξ0+X (A=Be, Cu, Pb) and for p+Be→Ξ¯0+X. Data were taken at angles of 0, 2, 3.5, 7.3, and 9.8 mrad between the incident 400-GeV proton beam and the outgoing hyperon beam. Production cross sections for Λ and Λ¯ production were measured at the same time. The A dependence of the Ξ0 cross sections is discussed, along with interpretations in terms of various models.

Cross sections for the inclusive processes p+A→KS0+X and p+A→Λ0+X (A=Be, Cu, and W) have been measured for incident protons at 12 GeV. Data are obtained at five laboratory production angles of 3.5°, 5.0°, 6.5°, 8.0°, and 9.5°, covering the kinematic range 0.3≤xF≤0.8 and 0.4≤pT≤1.3 GeV/c for KS0’s and 0.2≤xF≤0.9 and 0.4≤pT≤1.7 GeV/c for Λ0’s. The results are discussed in terms of the pT dependence, the xF dependence, the A dependence, the cross-section ratio KS0/Λ0, and triple-Regge behavior. The A dependence of KS0 and Λ0 spectra is analyzed in the constituent-quark model. The average pT2’s of quarks and diquarks involved in the KS0 and Λ0 production processes are discussed.
