A geometrical approach to N=2 super Yang-Mills theory on the two dimensional lattice
Simon Catterall
We propose a discretization of two dimensional Euclidean Yang-Mills theories with N=2 supersymmetry which preserves exactly both gauge invariance and an element of supersymmetry. T…

Lattice Study of the O(3) Supersymmetric Sigma Model
Sofiane Ghadab
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 latti…

Lattice Supersymmetry via Twisting
Simon Catterall
We describe how the usual supercharges of extended supersymmetry may be {\it twisted} to produce a BRST-like supercharge . The usual supersymmetry algebra is then replaced by a…
