Scattering solutions of Bethe-Salpeter equation in Minkowski and Euclidean spaces

Abstract

We shortly review different methods to obtain the scattering solutions of the Bethe-Salpeter equation in Minkowski space. We emphasize the possibility to obtain the zero energy observables in terms of the Euclidean scattering amplitude.
