Exact lattice Ward-Takahashi identity for the N=1 Wess-Zumino model
Marisa Bonini, Alessandra Feo
We consider a lattice formulation of the four dimensional N=1 Wess-Zumino model that uses the Ginsparg-Wilson relation. This formulation has an exact supersymmetry on the lattice.…

Exact supersymmetry on the lattice: the Wess-Zumino model
Marisa Bonini, Alessandra Feo
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…

Wess-Zumino model with exact supersymmetry on the lattice
Marisa Bonini, Alessandra Feo
A lattice formulation of the four dimensional Wess-Zumino model that uses Ginsparg-Wilson fermions and keeps exact supersymmetry is presented. The supersymmetry transformation that…
