Relations among Supersymmetric Lattice Gauge Theories via Orbifolding

Damgaard, Poul H., Matsuura, So

Understand

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.
