De Sitter Vacua from Matter Superpotentials

TL;DR

This paper explores how de Sitter and Minkowski vacua can be achieved through hidden sector matter interactions in string theory, explaining small supersymmetry breaking scales and soft term patterns.

Contribution

It introduces a novel approach where matter interactions in the hidden sector generate de Sitter vacua and specific supersymmetry breaking patterns.

Findings

Small supersymmetry breaking scale explained by gaugino condensation

Matter-dominated supersymmetry breaking scenario identified

Mirage mediation pattern of soft terms derived

Abstract

Consistent uplifting of AdS vacua in string theory often requires extra light degrees of freedom in addition to those of a (Kaehler) modulus. Here we consider the possibility that de Sitter and Minkowski vacua arise due to hidden sector matter interactions. We find that, in this scheme, the hierarchically small supersymmetry breaking scale can be explained by the scale of gaugino condensation and that interesting patterns of the soft terms arise. In particular, a matter-dominated supersymmetry breaking scenario and a version of the mirage mediation scheme appear in the framework of spontaneously broken supergravity.
