TL;DR

This paper explores how partial supersymmetry breaking in flat space can be achieved through three dual representations, leading to dual N=2 supergravities and supersymmetry algebras, highlighting the versatility of supersymmetry models.

Contribution

It introduces a novel approach to partial supersymmetry breaking using dual representations of the massive N=1 multiplet, expanding the understanding of supersymmetry algebra structures.

Findings

Three dual representations enable partial supersymmetry breaking.

UnHiggsing these representations yields dual N=2 supergravities.

The work demonstrates the equivalence and versatility of different supersymmetry formulations.

Abstract

The partial breaking of supersymmetry in flat space can be accomplished using any one of three dual representations for the massive N=1 spin-3/2 multiplet. Each of the representations can be ``unHiggsed'', which gives rise to a set of dual N=2 supergravities and supersymmetry algebras.
