Inspire Record 8878 DOI 10.17182/hepdata.4164

We have studied inclusive KS0, Λ, and Λ¯ production in π+d interactions at 24 GeV/c. The observed cross sections are 2.5±0.13 mb for KS0, 1.62±0.09 mb for Λ, and 0.12±0.02 mb for Λ¯. Longitudinal- and transverse-momentum distributions of the produced particles are presented. The average charged multiplicities of the system associated with a KS0 or with a Λ are presented and discussed. A nonzero average Λ polarization (-0.10±0.03) is observed. The x distribution of the backward (forward) KS0 and Λ produced in the reaction are in agreement with the x distribution of valence quarks in nucleons in nuclear target (pion beam), as predicted by the quark-recombination model of particle production applied to nuclear targets.

The polarization of 26 000 Σ+ hyperons produced by 400-GeV protons on Be has been measured. The polarizations of Σ+ and Λ hyperons have the opposite sign. The magnitude increases with momentum at 5-mrad production angle, and averages 22% over the momentum range 140 to 280 GeV/c.

K+ p and k+ d total cross-sections in the momentum range 0.57-1.16 gev/c

K+p and K+d total cross sections were measured in the momentum range 0.57-1.16 GeV/c using a secondary, separated kaon beam of the Lawrence Berkeley Laboratory Bevatron and conventional transmission-counter techniques. No evidence was found for structure in the cross section of either reaction as previously indicated near 0.7 GeV/c.

INCLUSIVE K0, LAMBDA0, K*+- (890), AND SIGMA*+- (1385) PRODUCTION IN P P COLLISIONS AT 300-GEV/C

Inspire Record 158990 DOI 10.17182/hepdata.24150

Inclusive K0K¯0, Λ0, and Λ¯0 cross sections have been determined using a 292-event/mb exposure of the hydrogen-filled 15-foot bubble chamber at Fermilab. From the invariant-mass distributions of V0π± pairs we find that σ(K*±(890))=4.4±1.4 mb, σ(Σ*±(1385))=0.54±0.40 mb, and σ(Σ¯*±(1385))=0.45±0.34 mb. It is estimated that 0.32 ± 0.11 of K0K¯0's, 0.21 ± 0.16 of Λ's, and 0.96 ± 0.75 of Λ¯'s originate from decays of K*(890) and Σ*(1385), respectively.

MEASUREMENT AND PARTIAL WAVE ANALYSIS OF THE REACTION K- P ---> K0(S) PI+ PI- N AT 6-GEV/C

We have performed a partial-wave analysis of the reaction K−p→KS0π+π−n at 6 GeV/c. We present the results of the analysis of about 4500 events in the low-t region (|t′|<0.2 GeV2) for the dominant waves in the 1200-to-2000-MeV mass range. We observe the 2+ K*(1430) and clear signals for the 1+ Q2(1400) and the 3− K*(1800). We find a new 1− resonance at about 1500 MeV and have some evidence for another 1− resonance at 1800 MeV. We also present the results of a partial-wave analysis as a function of t in the 1430-MeV mass region.

Energy dependence of the Lambda/Sigma0 production cross section ratio in p p interactions.

Kowina, P. ; Wolke, M. ; Adam, H.H. ; et al.
Eur.Phys.J.A 22 (2004) 293-299, 2004.
Inspire Record 644074 DOI 10.17182/hepdata.31762

The production of the Lambda and Sigma0 hyperons has been measured via the pp->pK+Lambda / Sigma0 reaction at the internal COSY-11 facility in the excess energy range between 14 and 60 MeV. The transition of the Lambda/Sigma0 cross section ratio from about 28 at Q<=13 MeV to the high energy level of about 2.5 is covered by the data showing a strong decrease of the ratio between 10 and 20 MeV excess energy. Effects from the final state interactions in the p-Sigma0 channel seem to be much smaller compared to the p-Lambda one. Estimates of the effective range parameters are given for the N-Lambda and the N-Sigma systems.

Lambda p interactions in momentum range 300 to 1500 mev/c

Kadyk, J.A. ; Alexander, G. ; Chan, J.H. ; et al.
Nucl.Phys.B 27 (1971) 13-22, 1971.
Inspire Record 68765 DOI 10.17182/hepdata.33624

A sample of approximately 250 Λp interactions has been obtained in the Λ-hyperon momentum range of about 300 to 500 MeV/ c . An enhanced Λ-hyperon production rate was obtained by exposing an internally-mounted platinum target to the incident 1.5 GeV/ c meson beam. Cross sections and angular distributions are obtained for the reactions: Λ p → Λ p, Λ p → Σ o p and Λ p → Λ p π o . In the elastic channel, no strong evidence is seen near the Σ o p threshold for the presence of a 3 S 1 resonance, which has been reported, although there is some evidence for a small enhancement in this mass region. There is evidence for the presence of P-waves and probably also D-waves above about 800 MeV/ c , but not below this momentum.
