Recent progress and future prospects of hyperon nucleon scattering experiment

Abstract: A new hyperon-proton scattering experiment, dubbed J-PARC E40, was performed to measure differential cross sections of the Σ+p, Σ−p elastic scatterings and the Σ−p → Λn scattering by identifying a lot of Σ particles in the momentum ranging from 0.4 to 0.8 GeV/c produced by the π±p → K+Σ± reactions. We successfully measured the differential cross sections of these three channels with a drastically improved accuracy with a fine angular step. These new data will become important experimental constraints to improv… Show more

“…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.…”
