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 DallʼAgata et al. (2012) [1], we can obtain de Sitter vacua with arbitrarily flat tachyonic directions in the SO(4,4)c 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 DallʼAgata et al. (2012) [1], we can obtain de Sitter vacua with arbitrarily flat tachyonic directions in the SO(4,4)c models.File in questo prodotto:
