Abstract: DE.00003 : Analysis Status of Σ-p Scattering Experiment at J-PARC*
9:30 AM–9:45 AM
Systematic knowledge in the interaction between baryons including the strangeness sector is still limited. Therefore study of ΣN interaction from scattering experiment data is needed to draw clear picture of the ΣN interaction. We proposed Σp scattering experiment (J-PARC E40) to study ΣN interaction with a high statistics
J-PARC E40 is an experiment to measure differential cross sections of both of Σ+p and Σ-p elastic scatterings and also Σ-p -> Λn inelastic scattering in the momentum range of 400--700 MeV/c. The experiment is performed in the K1.8 beam line at the J-PARC hadron hall. Σ production event in πp -> ΣK reaction in a liquid hydrogen target is detected with the KURAMA spectrometer, and following Σp scattering event is detected with the scattering proton detector (CATCH).
In this February and June of 2018, the detector commissioning has been performed. We took calibration data and a part of Σ- production data. In this talk, we would like to report the analysis status.
