A New Handle on de Sitter Compactifications

TL;DR

This paper introduces a novel class of de Sitter and anti de Sitter vacua in string theory through flux compactifications on Riemann surfaces, with perturbative effects stabilizing moduli and dominating over quantum corrections.

Contribution

It presents a new method for constructing stable de Sitter vacua using flux compactifications with dominant perturbative effects, enabled by tuning flux and brane quantum numbers.

Findings

Constructed large classes of de Sitter and anti de Sitter vacua.

Perturbative effects dominate over quantum corrections in stabilization.

Stability achieved through tuning flux and brane parameters.

Abstract

We construct a large new class of de Sitter (and anti de Sitter) vacua of critical string theory from flux compactifications on products of Riemann surfaces. In the construction, the leading effects stabilizing the moduli are perturbative. We show that these effects self-consistently dominate over standard estimates for further $\alpha^\prime$ and quantum corrections, via tuning available from large flux and brane quantum numbers.
