Abstract
The possibility of solving the Bethe–Salpeter equation in Minkowski space, even for fermionic systems, is becoming actual, through the applications of well-known tools: (1) the Nakanishi integral representation of the Bethe–Salpeter amplitude and (2) the light-front projection onto the null-plane. The theoretical background and some preliminary calculations are illustrated, in order to show the potentiality and the wide range of application of the method.
