# Goldstino superfields in N=2 supergravity

## TL;DR

This paper constructs off-shell N=2 supergravity models with spontaneously broken supersymmetry, incorporating Goldstino superfields, and explores their capacity to admit de Sitter vacua, extending previous rigid supersymmetry results.

## Contribution

It introduces new off-shell N=2 supergravity actions coupled with Goldstino superfields, enabling de Sitter vacua and including a novel reducible N=1 Goldstino supermultiplet.

## Key findings

- Models exhibit spontaneously broken local supersymmetry.
- Certain parameter choices allow for de Sitter vacua.
- New reducible N=1 Goldstino supermultiplet described.

## Abstract

We present off-shell N=2 supergravity actions, which exhibit spontaneously broken local supersymmetry and allow for de Sitter vacua for certain values of the parameters. They are obtained by coupling the standard N=2 supergravity-matter systems to the Goldstino superfields introduced in arXiv:1105.3001 and arXiv:1607.01277 in the rigid supersymmetric case. These N=2 Goldstino superfields include nilpotent chiral and linear supermultiplets. We also describe a new reducible N=1 Goldstino supermultiplet.
