Hyperon nucleon interactions in the p p ---> K+ Lambda p reaction
Sep, 1999Citations per year
Abstract:
We present calculations of the invariant mass spectra of the p system for the exclusive reaction with the aim of studying the final state interaction between the -hyperon and the proton. The reaction is described within a meson exchange framework and the final state interaction is incorporated through an off-shell t-matrix for the scattering, constructed using the available hyperon-nucleon (YN) potentials. The cross sections are found to be sensitive to the type of YN potential used especially at the and production thresholds. Hence, data on this exclusive reaction, which can be used to constrain the YN potentials are desirable.- p p: exclusive reaction
- mass spectrum: (Lambda p)
- p Lambda: final-state interaction
- nucleon hyperon: interaction
- meson: exchange
- p Lambda: elastic scattering
- potential: transition
- Feynman graph
- numerical calculations: interpretation of experiments
- p p --> Lambda p K+
