The Scaling of the No Scale Potential and de Sitter Model Building

TL;DR

This paper introduces a new approach to de Sitter model building that avoids the need for antibranes by finding nonzero local minima of the no-scale potential in string compactifications.

Contribution

It presents a variant of the KKLT construction that sources the volume modulus without antibranes, demonstrated through explicit examples in a toroidal orientifold.

Findings

Identified nonzero local minima of the no-scale potential in specific models.

Provided explicit examples in a simple toroidal orientifold.

Showed the potential to source the volume modulus without antibranes.

Abstract

We propose a variant of the KKLT (A)dS flux vacuum construction which does not require an antibrane to source the volume modulus. The strategy is to find nonzero local minima of the no-scale potential in the complex structure and dilaton directions in moduli space. The corresponding no-scale potential expanded about this point sources the volume modulus in the same way as does the antibrane of the KKLT construction. We exhibit explicit examples of such nonzero local minima of the no-scale potential in a simple toroidal orientifold model.
