  Supersymmetric models, in most cases, suffer from the lack of
non-perturbative techniques. Recently, an approach based on Dyson-Schwinger
equations has been proposed for the massless Wess-Zumino model. In this case,
the equations for the self-energies of the fields were solved with the strong
ansatz to take them all equal. We show, by numerically solving the equations,
that this is a too strong choice as also solutions with all different
self-energies are acceptable and more generic. This could have interesting
implications for supersymmetry breaking.
