It is shown that the lattice Wess-Zumino model written in terms of Ginsparg- Wilson fermions is invariant under a generalized supersymmetry transformation which is determined by an iterative procedure in the coupling constant. This transformation is nonlinear in the scalar fields and depends on the superpotential parameters. The implications of this lattice invariance are discussed.

Abstract
It is shown that the lattice Wess-Zumino model written in terms of Ginsparg- Wilson fermions is invariant under a generalized supersymmetry transformation which is determined by an iterative procedure in the coupling constant. This transformation is nonlinear in the scalar fields and depends on the superpotential parameters. The implications of this lattice invariance are discussed.File in questo prodotto:
