Supersymmetric CPN Sigma Model on Noncommutative Superspace
Takeo Inami, Hiroaki Nakajima
Abstract
We construct a closed form of the action of the supersymmetric CPN sigma model on noncommutative superspace in four dimensions. We show that this model has N=1/2 supersymmetry and that the transformation law is not modified. The supersymmetric CPN sigma model on noncommutative superspace in two dimensions is obtained by dimensional reducing the model in four dimensions.
