Nonlinear N=2 global supersymmetry
Abstract
We study the partial breaking of N=2 global supersymmetry, using a novel formalism that allows for the off-shell nonlinear realization of the broken supersymmetry, extending previous results scattered in the literature. We focus on the Goldstone degrees of freedom of a massive N=1 gravitino multiplet which are described by deformed N=2 vector and single-tensor superfields satisfying nilpotent constraints. We derive the corresponding actions and study the interactions of the superfields involved, as well as constraints describing incomplete N=2 matter multiplets of non-linear supersymmetry (vectors and single-tensors).
