Noncommutative perturbation in superspace

We consider noncommutative N=4 supersymmetric U( N) Yang–Mills theory. Using the N=1 superfield formalism and the background field method we compute one-loop four point contributions to the effective action and compare the result with the field theory limit from open string amplitudes in the presenc...

Description
Summary:We consider noncommutative N=4 supersymmetric U( N) Yang–Mills theory. Using the N=1 superfield formalism and the background field method we compute one-loop four point contributions to the effective action and compare the result with the field theory limit from open string amplitudes in the presence of a constant B-field.
