Resonances and final state interactions in the reaction pp → pK +
نویسندگان
چکیده
A study of the strangeness production reaction pp→pK + Λ for excess energies of ǫ ≤ 150 MeV, accessible at high-luminosity accelerator facilities like COSY, is presented. Methods to analyze the Dalitz plot distribution and angular spectra in the Jackson and helicity frames are worked out and suitable observables for extracting information on low lying resonances that couple to the KΛ system and for determining the Λp effective-range parameters from the final state interaction are identified and discussed. Furthermore, the chances for identifying the reaction mechanism of strangeness production are investigated.

We investigate the pp → pK + Λ reaction within an effective Lagrangian model where the contributions to the amplitudes are taken into account within the tree level. The initial interaction between the two nucleons in modeled by the exchange of π, ρ, ω and σ mesons and the ΛK + production proceeds via the excitation of the N * (1650), N * (1710), N * (1720) baryonic resonances.

متن کاملSummary of the COSY-11 Measurements of Hyperon Production
The studies of hyperon production performed at COSY-11 are summarized. The results of the experiments in the reaction channels pp → pK+Λ, pp → pK+Σ0, and pp → nK+Σ+ are shown. Excitation functions from threshold up to about 90 MeV excess energies have been evaluated with high precision for the Λ and Σ0 production. The Λp and Σ0 p final state interactions were extracted. The Σ+ production was me...

Motivated by the ongoing discussion concerning the nature of the scalar resonances f 0 (980) and a 0 (980), the COSY-11 collaboration has taken exclusive data on the pp → ppK + K − reaction near the production threshold. A first total cross section σ = (1.80 ± 0.27 +0.28 −0.35) nb for the excess energy Q = 17 MeV has been determined. In contrary to the η, ω, and η ′ single meson production stud...
