Single Pion Production Process in Pion-Nucleon Collision and the Sakata Model

Abstract:

Based on the Sakata model, we propose a model for the single pion production process in π-N collision which is essentially an extension of the Lindenbaum-Sternheimer model. It is pointed out that the analyses of sub-Bev single pion production phenomena will give us useful information about the level scheme of the Sakata Model. As a first step of the investigation of this model an analysis of the single pion production process in π+-p collision at 500 Mev is made. Our model predicts the contribution of the I=2 boson isobar as well as the I=3/2 fermion isobar (Lindenbaum-Sternhemier model) for this process. Such a prediction is consistent with the present experimental branching ratio (π++p→π++π0+p)/(π++p→π++π++n)=1.5. We calculate the energy and angular distribution of the pion and nucleon which will be useful for obtaining information about the I=2 boson isobar and I=3/2 fermion isobar from this process.
