Scientific paper
A covariant model of elastic pion-nucleon scattering based on the
Bethe-Salpeter equation is presented. The kernel consists of s- and u-channel
nucleon and delta poles, along with rho and sigma exchange in the t-channel. A
good fit is obtained to the s- and p-wave phase shifts up to the two-pion
production threshold.
