arXiv:2206.09971 · doi:10.1103/PhysRevD.106.066012

Abstract

We analyze the vacuum structure of supergravity coupled to 9 vector multiplets with gauge group . Aside from the central AdS vacuum at the origin, on which the supermultiplet structure reproduces the massless sector of M-theory compactified on , we find a rich structure of AdS vacua preserving supersymmetry. These new vacua are arranged in a manifold spanned by scalar fields corresponding to exactly marginal deformations of the dual CFT. This manifold has the form , where is a discrete subgroup of the gauge group: and vacua correspond, respectively, to a point, a line and a surface in the three-dimensional vacuum manifold. We study RG flows from the central vacuum and elaborate on the possible higher dimensional origin of the new vacua. For the reader's convenience we also provide a review of the embedding tensor formulation of , gauged supergravities. In particular we provide formulas involving the fermion shift tensors and mass matrices in theories, which can be applied to a generic gauging.
