| Abstract: |
An explicit example for a de Sitter vacuum in type IIB string theory will be presented. After deriving a sufficient condition for de Sitter vacua in the K\"ahler uplifting scenario, it is shown that a globally consistent de Sitter model can be realized on a certain Calabi-Yau, stabilizing all geometric moduli and fulfilling all known consistency constraints. The complex structure moduli stabilization by fluxes is studied explicitly for a small number of cycles. Extrapolating to a larger number offlux carrying cycles, statistical studies in the literature are verified, showing that in principle the string landscape can account for a universe with an extremely small cosmological constant. |
