The five dimensional version of the Green-Schwarz mechanism can be invoked to cancel abelian anomalies on the boundaries of brane world models. In five dimensions there are two dual descriptions that employ either a two-form tensor field or a vector field. We present the supersymmetric extensions of these dual theories using four-dimensional superspace. The vector formulation always contains singular boundary mass terms which are absent in the tensor formulation. This apparent inconsistency is resolved by showing that in either formulation the propagator of the anomalous U(1) gauge (super)field exhibits finite (non-local) boundary mass terms, which generically lead to a finite nonzero mass for the lowest lying Kaluza-Klein mode. Talk based on the work done in collaboration with T. Gherghetta and S. Groot-Nibbelink.
