Decoupling and de Sitter vacua in approximate no-scale supergravities
2015
Journal of High Energy Physics
We study N=1 supergravity with N>1 chiral superfields in which one of the fields has a Kähler potential of exact no-scale type. Such systems admit de Sitter (dS) solutions in which supersymmetry is predominantly broken by the no-scale field, with only a small contribution to the breaking coming from the other fields. Metastable dS vacua of this type were recently shown to be achievable by the finetuning of an N× N sub-matrix of the Hessian matrix at the critical point. We show that
