We provide a simple construction of supersymmetric vacua, including some with orientifold descriptions. These vacua, which have warp factors, typically have fewer moduli than conventional Calabi-Yau compactifications. The mechanism for anomaly cancellation in the orientifold models involves background RR and NS fluxes. We consider in detail an orientifold of $K3\\times T^2$ with background fluxes. After a combination of T and S-dualities, this type IIB orientifold is mapped to a compactification of the SO(32) heterotic string on a non-Kahler space with torsion.", "revisions": [ { "version": "v3", "updated": "2001-09-25T02:26:18.000Z" } ], "analyses": { "keywords": [ "background fluxes", "type iib orientifold", "conventional calabi-yau compactifications", "simple construction", "ns fluxes" ], "tags": [ "journal article", "famous paper" ], "publication": { "publisher": "IOP", "journal": "J.
