Abstract
We analyse the vacuum structure of isotropic Z2 × Z2 flux compactifications, allowing for a single set of sources. Combining algebraic geometry with supergravity tech niques, we are able to classify all vacua for both type IIA and IIB backgrounds with arbitrary gauge and geometric fluxes. Surprisingly, geometric IIA compactifications lead to a unique theory with four different vacua. In this case we also perform the general analy sis allowing for sources compatible with minimal supersymmetry. Moreover, some relevant examples of type IIB non-geometric compactifications are studied. The computation of the full N = 4 mass spectrum reveals the presence of a number of non-supersymmetric and nevertheless stable AdS4 vacua. In addition we find a novel dS4 solution based on a non-semisimple gauging.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
