On Type IIB moduli stabilization and image supergravities Original Research Article

We analyze image compactifications of Type IIB theory with generic, geometric and non-geometric, dual fluxes turned on. In particular, we study image toroidal orbifold compactifications that admit an embedding of the untwisted sector into gauged image supergravities. Truncations, spontaneous breaking of supersymmetry and the inclusion of sources are discussed. The algebraic identities satisfied by the supergravity gaugings are used to implement the full set of consistency constraints on the background fluxes. This allows to perform a generic study of image vacua and identify large regions of the parameter space that do not admit complete moduli stabilization. Illustrative examples of AdS and Minkowski vacua are presented.
