Establishment of a Modern Experimental Technique of a \(\Sigma p\) Scattering Experiment at J-PARC

A part of the experiment was performed in 2018 and 2019 in J-PARC. As a result of analyzing the collected data, the \(\Sigma ^{ - }\) production and the \(\Sigma ^{ - }p\) scattering reaction have been identified. It means that our new measurement and analysis method are successfully working well. Analysis for deriving the differential cross section of the \(\Sigma p\) scattering is on going.
