Meson-exchange $\pi N$ Models in Three-Dimensional Bethe-Salpeter Formulation

Cheng-Tsung Hung, Shin Nan Yang, T. -S. H. Lee

The pion-nucleon scattering is investigated by using several three-dimensional reduction schemes of the Bethe-Salpeter equation for a model Lagrangian involving $\pi$, $N$, $\Delta$, $\rho$,…
