Separable Bethe-Salpeter equation kernels for pion-nucleon scattering

Abstract
In a previous paper we solved the Bethe-Salpeter equation with separable interactions and demonstrated the applicability of the method for the most important nucleon-nucleon partial waves. In this paper we use the Bethe-Salpeter equation for pion nucleon partial waves including the necessary two potential ansatz for the P11 wave. A fully relativistic treatment of the πd system can be performed with these amplitudes.
