Abstract

We scan the landscape of flux compactifications for the Calabi-Yau manifold 4 [1,1,1,6,9] with two Kähler moduli by varying the value of the flux superpotential W 0 over a large range of values. We do not include uplift terms. We find a rich phase structure of AdS and dS vacua. Starting with W 0 ∼ 1 we reproduce the exponentially large volume scenario, but as W 0 is reduced new classes of minima appear. One of them corresponds to the supersymmetric KKLT vacuum while the other is a new, deeper non-supersymmetric minimum. We study how the bare cosmological constant and the soft supersymmetry breaking parameters for matter on D7 branes depend on W 0, for these classes of minima. We discuss potential applications of our results.
