Nonlinear $\mathcal{N}=2$ Global Supersymmetry

Abstract

We study the partial breaking of $\mathcal{N}=2$ 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 $\mathcal{N}=1$ gravitino multiplet which are described by deformed $\mathcal{N}=2$ 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 $\mathcal{N}=2$ matter multiplets of non-linear supersymmetry (vectors and single-tensors).

a comment of a few lines, not present in the already published version, was added in the end of section 3.1
