Abstract: (Springer)
A lattice Lagrangian of the Wess-Zumino model is constructed using perturbation theory up to two loops. It is shown that the renormalized vertex-functions have the correct continuum limit if nonsupersymmetric counterterms up to dimension four are added to the Lagrangian. The structure of these terms is analysed with the Wilson prescription for the fermions.
