# De Sitter vacua in string theory

@article{Kachru2003DeSV, title={De Sitter vacua in string theory}, author={Shamit Kachru and Renata Kallosh and Andrei Linde and Sandip P. Trivedi}, journal={Physical Review D}, year={2003}, volume={68}, pages={046005} }

We outline the construction of metastable de Sitter vacua of type IIB string theory. Our starting point is highly warped IIB compactifications with nontrivial NS and RR three-form fluxes. By incorporating known corrections to the superpotential from Euclidean D-brane instantons or gaugino condensation, one can make models with all moduli fixed, yielding a supersymmetric AdS vacuum. Inclusion of a small number of {ovr D3} branes in the resulting warped geometry allows one to uplift the AdS…
