Abstract [en]

We study a class of orientifold compactifications of type IIB supergravity with fluxes down to 4D in connection with truncations of half-maximal gauged supergravities yielding isotropic STU-models with minimal supersymmetry. In this context, we make use of a group-theoretical approach in order to derive flux-induced superpotentials for different IIB backgrounds. We first review the toroidal case yielding CEP-like superpotentials characterised by their no-scale behaviour. We then turn to S-3 x S-3 and S-3 x T-3, which, surprisingly, give rise to effective descriptions of non-geometric Q- and P-fluxes through globally geometric non-toroidal compactifications. As a consequence, such constructions break the no-scale symmetry without invoking any non-perturbative effects.
