Gaugings at angles from orientifold reductions

TL;DR

This paper explores how orientifold reductions lead to N=4 gauged supergravity in four dimensions with gauge groups having relative angles, which are important for moduli stabilization and de Sitter vacua.

Contribution

It demonstrates that gaugings at angles naturally emerge in orientifold reductions, providing new insights into moduli stabilization and de Sitter vacua in supergravity.

Findings

Gaugings at angles are a generic feature of orientifold reductions.

Such gaugings are crucial for stabilizing moduli.

They enable the construction of de Sitter vacua.

Abstract

We consider orientifold reductions to N=4 gauged supergravity in four dimensions. A special feature of this theory is that different factors of the gauge group can have relative angles with respect to the electro-magnetic SL(2) symmetry. These are crucial for moduli stabilisation and De Sitter vacua. We show how such gaugings at angles generically arise in orientifold reductions.
