The three-dimensional noncommutative nonlinear sigma model in superspace
We study the superspace formulation of the noncommutative nonlinear supersymmetric O(N) invariant sigma-model in 2+1 dimensions.We prove that the model is renormalizable to all orders of 1/N and explicitly verify that the model is asymptotically free.
