All homogeneous N=2 M-theory truncations with supersymmetric AdS4 vacua

Understand

We study consistent truncations of M-theory to gauged N=2 supergravity in four dimensions, based on a large class of SU(3)-structures in seven dimensions.

• We show that the gauging involves isometries of the vector multiplet scalar manifold as well as the Heisenberg algebra and a special isometry of the hyperscalar manifold.
• As a result, non-abelian gauge groups and new non-trivial scalar potentials are generated.
• Then we specialize to all homogeneous SU(3)-structures supporting supersymmetric AdS4 vacua.
