Symmetry and scaling in the Q-exact lattice (2,2) 2d Wess-Zumino model
arXiv:hep-lat/0508017
Abstract
As a nonperturbative check on the Q-exact lattice formulation, we demonstrate that the continuum R-symmetries are recovered. We locate the critical domain of the lattice theory. Aspects of the continuum nonrenormalization theorems are found to be respected at finite lattice spacing. Preliminary attempts to extract critical exponents--another nonperturbative check--are discussed. All of our results are obtained from Monte Carlo simulations with dynamical fermions.
