Stable de Sitter Vacua from N=2 Supergravity

TL;DR

This paper constructs stable de Sitter vacua within N=2 supergravity by employing non-abelian gaugings, de Roo-Wagemans angles, and Fayet-Iliopoulos terms, avoiding tachyonic instabilities.

Contribution

It introduces a novel method to achieve stable de Sitter vacua in N=2 supergravity using specific gaugings and rotations, expanding the landscape of viable supergravity models.

Findings

Stable de Sitter vacua found without tachyons

Requires non-abelian non-compact gaugings

Utilizes de Roo-Wagemans angles and Fayet-Iliopoulos terms

Abstract

We find extrema of the potential of matter couplings to N=2 supergravity that define de Sitter vacua and no tachyonic modes. There are three essential ingredients in our construction: namely non-abelian non-compact gaugings, de Roo-Wagemans rotation angles, and Fayet-Iliopoulos terms.
