Nucleon-antinucleon elastic scattering with inelastic effects: S-wave phase-shifts

The OBE model for N N elastic scattering is improved by including inelasticity a phenomenological level in a pure S-matrix formulation. In this way it is possible to find the π and η poles at their physical masses. The corresponding phase-shifts are computed and shown to be remarkably independent of...

Description
Summary:The OBE model for N N elastic scattering is improved by including inelasticity a phenomenological level in a pure S-matrix formulation. In this way it is possible to find the π and η poles at their physical masses. The corresponding phase-shifts are computed and shown to be remarkably independent of the inelasticiy parameters.
