Understanding of S N (I = 3/2, S = 1) interaction is a key to reveal the origin of the short range core in the baryon – baryon interactions because a large repulsive force is predicted to originate from Pauli effect in the quark level and S N interactions are also not understood well. Therefore the systematic study of S N channel is very important.
In order to investigate these topics, we have planed a S p scattering experiment (J-PARC E40) and will measure the differential cross sections of Σ+ p and Σ- p elastic scatterings and Σ- p -> Λ n inelastic scattering. In this experiment, we detect successive sets of two-body reactions in a liquid hydrogen target; p p -> S K+ by the spectrometers up/downstream from the target, and S p -> S p scattering event by the scattered proton detector surrounding the target (CATCH).
We started a Σ- p scattering experiment at first and took a part of the Σ- production data in June 2018 and we will report the analysis for Σ- yield.
