Nucleon-nucleon scattering above the pion production threshold

Journal Article · · Phys. Rev., C; (United States)
Starting from a simple nonrelativistic field theory of pions and nucleons, we derive linear integral equations coupling amplitudes of baryon number equal two systems. These equations guarantee two- and three-body unitarity above the threshold for single pion production, and include explicitly the coupling of the NN to (e.g.) N..delta.. and ..pi..d channels. The relationship of this approach to earlier schemes is discussed.
