Gaugings at angles from orientifold reductions
arXiv:0902.0479 · doi:10.1088/0264-9381/26/13/135009
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.
