A one-boson-exchange model for the hyperon-nucleon ( N, N ) interaction is presented. The model incorporates the standard one boson exchanges of the lowest pseudoscalar and vector meson multiplets with coupling constants fixed by SU(6) flavor symmetry relations. As the main new feature of the model, the contributions in the scalar-isoscalar (σ ) and vector-isovector (ρ) exchange channels are now constrained by a microscopic model of correlated ππ and KK exchange. Additional short-ranged ingredients of the model in the scalar-isovector (a 0 ) and scalar-isospin-1/2 (κ) channels are likewise viewed as arising from meson-meson correlations but are treated phenomenologically. With this model a satisfactory reproduction of the available hyperon-nucleon data can be achieved.

“…The data are based on 378 and 224 elastic Λp scattering events, respectively. They were taken by two independent groups [1,2] using the 81-cm hydrogen bubble chamber at CERN. The two data sets are consistent within the errors.…”

“…In addition the Y N interaction is needed for studies of hypernuclei. Experimental information on the Λp interaction has been obtained from Λp scattering experiments [1,2], the binding energies of hypernuclei [3,4], and studies of the Λp final state interaction (FSI). The Λp FSI was observed in strangeness transfer reactions [5] and in reactions with associated strangeness production π + + d → K + + (Λp) and p + p → K + + (Λp) [8,9,10,11,12,13,14,15].…”

The reaction pp → K + + (Λp) was measured at T p = 1.953 GeV and Θ = 0 • with a high missing mass resolution in order to study the Λp final state interaction. The large final state enhancement near the Λp threshold can be described using the standard Jost-function approach. The singlet and triplet scattering lengths and effective ranges are deduced by fitting simultaneously the Λp invariant mass spectrum and the total cross section data of the free Λp scattering.
