Supergravity algebras and Minkowski vacua in generalised flux compactifications.

In this talk, we present a new approach to the moduli stabilization problem at non supersymmetric Minkowski vacua for a set of T-duality invariant N=1 type IIB orientifold models with generalised fluxes. We perform a complete classification of the flux induced 12d algebras compatible with the orbifold symmetries and derive their characteristic Supergravity models. By identifying the effective parameter space, we present a complete phenomenological analysis of the Minkowski vacua allowed by the different models. Finally, by means of a IIB/IIA dictionary at the level of the scalar potential, we compare our results to previous ones in the literature.
