| Popis: | A simple, KKLT-like construction of de Sitter vacua in type IIA string theory is presented in an STU model with guidance from string theory U-duality and with an uplifting anti-D6-brane. In four dimensions the model is reduced to $\mathcal{N}=1$ supergravity with three chiral multiplets, namely $S$, $T$ and $U$, as well as one nilpotent multiplet representing the anti-D6-brane. Comment: 22 pages, 3 figures. v2: references added, discussion in section 3 improved. v3: references added, sections 2.3 and 4 improved, section 7 added. To be published in JHEP |
