International audienceIn order to test theoretical frameworks of the baryon–baryon (BB) interactions and to confirm the “Pauli effect between quarks” for the first time, we have proposed an experiment (J-PARC E40) to measure low-energy hyperon–proton scattering cross sections of the Σ^+p, Σ^−p elastic scatterings and the Σ^−p → Λn inelastic scattering in the momentum range of 400 < p (MeV/c) < 700 in the laboratory system. Experimentally, we detect two successive reactions of the Σ production (π^±p → K^+Σ^±) and the Σp scattering (Σp → Σp) in the same liquid hydrogen target. The former is measured with two magnetic spectrometers, and the latter with a scattered proton detector (CATCH). By using a high intensity π beam, we estimate that more than 10,000 scattering events can be identified. In this experiment, we aim to provide good quality scattering data to test the theoretical models of the BB interaction
