Data on multiplicity, correlations, and inclusive spectra of KS0 mesons and Λ0(Λ¯0) hyperons produced with xF≤0 in inelastic pNe20 and pN interactions at 300 GeV are presented and compared. The inclusive cross sections for pNe20 (pN) with xF≤0 are 61.1±2.8 mb (3.34±0.64 mb) for KS0, 40.8±2.5 mb (1.89±0.29 mb) for Λ0, and 3.9±0.5 mb (0.31±0.08 mb) for Λ¯0. The multiplicity ratio for pNe20 and pN interactions is 1.58±0.16 for KS0, 1.95±0.23 for Λ0, and 1.12±0.43 for Λ¯0. We have observed the Σ0(1193) hyperon and measured the average multiplicity (nΣ0=0.049±0.027) for xF≤0. We have also observed the strange resonances K*(892), K*(1415), and Σ*(1385) with xF≤0 and measured the fraction of V0 coming from each resonance. Λ0 polarization for xF≤0 is measured and shows a decrease as p⊥ increases [pΛ(pNe20)≈−0.25 at p⊥=1.5 GeV/c], in agreement with other experiments which measure polarization in the region xF≫0. Since (43±7)% of the Λ0 are produced in Σ0→Λ0γ decays, the Λ0 polarization is significantly greater than the measured values. Experimental results are compared to predictions of the Lund model and the dual parton model of soft hadron-nucleus and hadron-nucleon interactions.

EXPERIMENTAL STUDY OF THE pi+ p ---> K+ SIGMA+ REACTION AT 12-GeV/c

The results of the study of the π + p→K + ∑ + (1) and π + p→K + ∑ + (1385) (2) reactions at 12 GeV/ c are presented. The differential cross sections d σ /d t in| t min |<| t |<0.8 (GeV/ c ) 2 momentum transfer range are measured. The ∑ + polarisation for | t |<0.5 (GeV/ c ) 2 for reaction (1) is defined. Binary reactions (1) and (2) were selected by analyzing the missing mass spectra for the forward emitted fast K + meson. The total cross sections in the studied momentum transfer range are 20.2±2.4 μ b and 7.3±1.1 μ b for the reactions (1) and (2) respectively. The experimental results are compared with the predictions of the Regge models which take into account rescattering and secondary singularities.
