We show how to derive Catterall's supersymmetric lattice gauge theories directly from the general principle of orbifolding followed by a variant of the usual deconstruction.
- These theories are forced to be complexified due to a clash between charge assignments under U(1)-symmetries and lattice assignments in terms of scalar, vector and tensor components for the fermions.
- Other prescriptions for how to discretize the theory follow automatically by orbifolding and deconstruction.
- We find that Catterall's complexified model for the two-dimensional N=(2,2) theory has two independent preserved supersymmetries.
