Some Aspects of Lambda Production in the Exclusive Reactions K- p --> Lambda0 (n) Pions at 8.25-GeV/c

The ATHENS-DEMOCRITOS-LIVERPOOL-VIENNA collaboration Girtler, P. ; Markytan, M. ; Dallman, D.P. ; et al.
Nucl.Phys.B 99 (1975) 13-29, 1975.
Inspire Record 104142 DOI 10.17182/hepdata.31862

Cross sections are given for the various exclusive reactions K − p→ Λ 0 + n pions, as well as for quasi two-body final states involving ϱ 0 , ω 0 and Y 1 ∗ (1385) resonance production. The general features of Λ 0 production are presented as a function of the pion multiplicity n . Production of Y 1 ∗+ (1385) is clearly observed at all multiplicities while the Y 1 ∗− (1385) signals grow with the multiplicity, as expected in a non-exotic exchange picture. The polarisation of the Λ 0 is consistent with zero everywhere, except when it is a decay product of Y 1 ∗ (1385), when non-zero values are found for odd values of n . The reactions Λ 0 + 2π and Λ 0 + 3π are analysed in terms of the Plahte-Roberts model and good overall agreement is obtained for the various effective mass distributions and the p L ∗ , p T and cos θ distributions for the individual particles.

Inspire Record 75019 DOI 10.17182/hepdata.32867

We present complete results concerning the five reactions K − p → Λω , K − p → Λφ , K − p → Σ 0 ϱ and K − p → Σ 0 φ . The experimental data are well described by exchange mechanisms and the agreement with the SU(3) symmetry predictions is excellent.
