Abstract

We have calculated the electromagnetic elastic form factor of a two body scalar bound state. The Bethe-Salpeter equation is solved directly in the Minkowski space using the Perturbation Theory Integral Representation. At soft coupling regime the obtained results are compared with those following from a quasipotential spectator (Gross) approximation.
