G. Dall'Agata, G. Inverso
TL;DR
This paper explores the existence of de Sitter vacua with flat tachyonic directions in maximal gauged supergravity models, utilizing recent deformations to identify conditions for such vacua.
Contribution
It demonstrates that de Sitter vacua with arbitrarily flat tachyonic directions can be achieved in SO(4,4)c models using newly introduced deformed theories.
Findings
Existence of de Sitter vacua with flat tachyonic directions.
Application of recent deformed theories to supergravity models.
Potential implications for cosmological models.
Abstract
In this letter we discuss de Sitter vacua in maximal gauged supergravity in 4 dimensions. We show that, using the newly deformed theories introduced in arxiv:1209.0760, we can obtain de Sitter vacua with arbitrarily flat tachyonic directions in the SO(4,4)c models.
