“…The repulsions in these channels were confirmed also in the lattice computation of the potential [24,25]. The E40 experiment at J-PARC was very successful in measuring the pΣ ± scattering cross sections recently [11,26]. The data are analyzed to extract the S-wave phase shifts, which show moderate N Σ repulsion at low and medium energies.…”

Short-range parts of the baryon-baryon (BB) interactions are analyzed from the spin-flavor SU (6) sf ⊃ SU (3) f × SU (2)s symmetry viewpoint. Due to the Pauli principle of quarks, the symmetry structure of the wave functions is restricted at short distances. Consequently, the BB states with the same spin-flavor quantum numbers may be reduced into one or a few spin-flavor states. Such reduction causes repulsion and/or suppression of transitions at short distances. We show that the observed suppression of the ΞN → ΛΛ conversion can be explained following the above argument. It is also applied to the suppression of the ΣN to ΛN conversion in the spin 1 and isospin 1/2 channel. Furthermore, the effects of the color-magnetic interaction (CMI), which prefers flavor antisymmetric states, to the Pauli-allowed states are discussed.

A hyperon–nucleon potential for the strangeness $$S=-1$$ S = - 1 sector ($$\varLambda N$$ Λ N , $$\varSigma N$$ Σ N ) up to third order in the chiral expansion is presented. SU(3) flavor symmetry is imposed for constructing the interaction, however, the explicit SU(3) symmetry breaking by the physical masses of the pseudoscalar mesons and in the leading-order contact terms is taken into account. A novel regularization scheme is employed which has already been successfully used in studies of the nucleon–nucleon interaction within chiral effective field theory up to high orders. An excellent description of the low-energy $$\varLambda p$$ Λ p , $$\varSigma ^- p$$ Σ - p and $$\varSigma ^+ p$$ Σ + p scattering data is achieved. New data from J-PARC on angular distributions for the $$\varSigma N$$ Σ N channels are analyzed. Results for the hypertriton and $$A=4$$ A = 4 hyper-nuclear separation energies are presented. An uncertainty estimate for the chiral expansion is performed for selected hyperon–nucleon observables.
