Scientific paper

A covariant model of elastic pion-nucleon scattering based on the
Bethe-Salpeter equation is presented. We obtain a good description of the S-
and P-wave phase shifts up to 360 MeV laboratory energy. We also compare
results from the K-matrix approach and several 3-dimensional quasipotential
equations to the Bethe-Salpeter equation.
