Abstract

We consider flux compactification of type II string theory with local sources on SU(3)-structure manifolds. By adding pseudo-calibrated anti-DpDp-branes wrapped on supersymmetric cycles we generalize all existing models so that the effective d=4,d=4, N=1{\cal N}=1 supergravity now includes a nilpotent multiplet. We present a new dictionary between string theory models and K{\"a}hler potential KK and superpotential WW for these dS supergravities with a nilpotent multiplet and non-linearly realized local supersymmetry. In addition to KKLT and LVS with uplifting D3\overline{D3}-branes, we have now new models with uplifting D5\overline{D5}, D6\overline{D6}, D7\overline{D7}, D9\overline{D9}-branes. The new uplifting contribution to the supergravity potential due to Volkov-Akulov supersymmetry is universal. As one application of our general result, we study classical flux compactifications of type IIA supergravity and find that a previously discovered universal tachyon is now absent.
