  We provide a current expansion for the classical equations of motion of the
massles Wess-Zumino model. In the low-energy limit, there appears a massive
behavior for bosonic degrees of freedom and, at small coupling, the fermion
field shows the same mass and supersymmetry is overall preserved. In the limit
of the coupling running to infinity, the fermion field displays a different
equation of motion, a Nambu-Jona-Lasinio-like one, and we cannot draw an
identical conclusion.
