On supersymmetric AdS4 orientifold vacua
In this work we study ten-dimensional solutions to type IIA string theory of the form AdS × X which contain orientifold planes and preserve N = 1 supersymmetry. In particular, we consider solutions which exhibit some key features of the four-dimensional DGKT proposal for compactifications on Calabi-...

| Sumario: | In this work we study ten-dimensional solutions to type IIA string theory of the form AdS × X which contain orientifold planes and preserve N = 1 supersymmetry. In particular, we consider solutions which exhibit some key features of the four-dimensional DGKT proposal for compactifications on Calabi-Yau manifolds with fluxes, and in this sense may be considered their ten-dimensional uplifts. We focus on the supersymmetry equations and Bianchi identities, and find solutions to these that are valid at the two-derivative level and at first order in an expansion parameter which is related to the AdS cosmological constant. This family of solutions is such that the background metric is deformed from the Ricci-flat one to one exhibiting SU(3) × SU(3)-structure, and dilaton gradients and warp factors are induced. |
