De Sitter vacua from anti-D3-branes in type IIB LVS compactifications

Abstract: We will begin with an introduction on moduli stabilisation in type IIB compactifications on CY orientifolds, with de Sitter uplift due to an anti-D3 brane. We consider a concrete setup where an anti D3-brane sits at the tip of a warped throat and the stabilised volume is exponentially large as in the large volume scenario (LVS). We analyse the conditions on the parameters of the EFT such that they are in the region of validity. We illustrate our results with an explicit choice of Calabi-Yau manifold and D-brane configuration, where moduli stabilisation gives rise to a de Sitter minimum.
