A Critique of the Link Approach to Exact Lattice Supersymmetry
Falk Bruckmann🇩🇪 · Simon Catterall🇺🇸 · Mark de Kok🇳🇱
Abstract
We examine the link approach to constructing a lattice theory of N=2 super Yang Mills theory in two dimensions. The goal of this construction is to provide a discretization of the continuum theory which preserves all supersymmetries at non-zero lattice spacing. We show that this approach suffers from an inconsistency and argue that a maximum of just one of the supersymmetries can be implemented on the lattice.
