Halving ISO(7) supergravity

Abstract

Half-maximal, $\mathcal{N}=4$, sectors of $D=4$ $\mathcal{N}=8$ supergravity with a dyonic ISO(7) gauging are investigated. We focus on a half-maximal sector including three vector multiplets, that arises as a certain $\text{SO}(3{)}_{\text{R}}$-invariant sector of the full theory. We discuss the embedding of this sector into the largest half-maximal sector of the $\mathcal{N}=8$ supergravity retaining six vector multiplets. We also provide its canonical $\mathcal{N}=4$ formulation and show that, from this perspective, our model leads in its own right to a new explicit gauging of $\mathcal{N}=4$ supergravity. Finally, expressions for the restricted duality hierarchy are given and the vacuum structure is investigated. Five new non-supersymmetric AdS vacua are found numerically. The previously known $\mathcal{N}=2$ and $\mathcal{N}=3$ AdS vacua are also contained in our $\mathcal{N}=4$ model. Unlike when embedded in previously considered sectors with fewer fields, these vacua exhibit their full $\mathcal{N}=2$ and $\mathcal{N}=3$ supersymmetry within our $\mathcal{N}=4$ model.
