Abstract

We scan the landscape of flux compactifications for the Calabi-Yau manifold Bbb P4[1,1,1,6,9] with two Kähler moduli by varying the value of the flux superpotential W0 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 W0 ∼ 1 we reproduce the exponentially large volume scenario, but as W0 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 W0, for these classes of minima. We discuss potential applications of our results.
