The Bethe-Salpeter equation and the Low Energy Theorems for \(\pi N\) scattering



The Bethe-Salpeter (BS) amplitude for \(\pi N\) scattering is evaluated at the off-mass-shell points corresponding to the Low Energy Theorems (LET) based on PCAC and current algebra. The results suggest a way of maintaining constructing between BS equation and LET.
