The supersymmetric extension of the Faddeev model Original Research Article

We study the supersymmetric extension of the Faddeev model in four dimensions. The Faddeev model contains three-dimensional soliton solutions and we are interested in how these solitons are affected by supersymmetry. We consider both the N=1 and N=2 extensions and find that in neither case it is possible to supersymmetrize the model without adding additional bosonic terms. There are essentially two ways of constructing the supersymmetric theory, one that will lead to a model which allows for solitons and another that gives a model where solitons are excluded.
