Lattice four-dimensional,N=4super-Yang-Mills studies are practical

Abstract

We show that nonpertubative lattice studies of four-dimensional N=4 super-Yang-Mills are within reach. We use Ginsparg-Wilson fermions to avoid gluino masses and an exact implementation of the (chiral) R-symmetry, which greatly limits the number of counterterms that must be fine-tuned. Only bosonic operators require fine-tuning, so all tunings can be done 'offline' by a Ferrenberg-Swendsen type reweighting. We show what measurables can be used to perform the tuning.
