On the finiteness of noncommutative supersymmetric QED/sub 3/ in the covariant superfield formulation
(2003) [Journal article]The three-dimensional noncommutative supersymmetric QED is investigated within the superfield approach. We prove the absence of UV/IR mixing in the theory at any loop order and demonstrate its one-loop finiteness. -
The three-dimensional noncommutative nonlinear sigma model in superspace
(2001) [Journal article]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 ...
