## TL;DR

This paper introduces a novel type of Fayet-Iliopoulos terms in ${\mathcal N}=2$ supergravity that enable stable de Sitter vacua without gauging the $R$-symmetry, expanding the possibilities for model building.

## Contribution

The paper presents a new class of FI terms in ${\mathcal N}=2$ supergravity that do not require $R$-symmetry gauging, allowing for stable de Sitter vacua with minimal field content.

## Key findings

- New FI terms do not require $R$-symmetry gauging.
- Models with a single vector multiplet can have stable de Sitter vacua.
- Comparison with standard FI terms highlights unique properties.

## Abstract

We present a new type of Fayet-Iliopoulos (FI) terms in ${\mathcal N}=2$ supergravity that do not require the gauging of the $R$-symmetry. We elaborate on the impact of such terms on the vacuum structure of the ${\mathcal N}=2$ theory and compare their properties with the standard Fayet-Iliopoulos terms that arise from gaugings. In particular, we show that, with the use of the new FI terms, models with a single physical ${\mathcal N}=2$ vector multiplet can be constructed that give stable de Sitter vacua.
