Constructing stable de Sitter in M-theory from higher curvature corrections

Understand

We consider dimensional reductions of M-theory on $\mathbb{T}^{7}/\mathbb{Z}_{2}^{3}$ with the inclusion of arbitrary metric flux and spacetime filling KK monopoles.

• With these ingredients at hand, we are able to construct a novel family of non-supersymmetric yet tachyon free Minkowski extrema.
• These solutions are supported by pure geometry with no extra need for gauge fluxes and possess a fully stable perturbative mass spectrum, up to a single flat direction.
• Such a direction corresponds to the overall internal volume, with respect to which the scalar potential exhibits a no-scale behavior.
