Abstract
We present preliminary numerical results from a lattice study of the two-dimensional O(3) non-linear sigma model. In the continuum this model possesses N=2 supersymmetry. The lattice formulation we use retains an exact (twisted) supersymmetry except for a soft breaking associated with a Wilson mass term needed to remove the doubles. Our numerical results show that the partition function is independent of coupling as predicted by supersymmetry.
