A Solution to the de Sitter Swampland Conjecture versus Inflation Tension via Supergravity

TL;DR

This paper uses supergravity methods to reconcile single-field slow-roll inflation with the de Sitter swampland conjecture, proposing a bounded conjecture compatible with inflationary models.

Contribution

It introduces a supergravity-based approach to derive a bounded de Sitter conjecture that aligns with slow-roll inflation for concave potentials.

Findings

Single-field slow-roll inflation is compatible with the bounded de Sitter conjecture.

Supergravity methods enable derivation of a non-positive F-term potential.

The approach harmonizes inflationary models with swampland constraints.

Abstract

The methods of supergravity allow us to derive a multi-field F-term potential. Using this, we denote a generic and non-positive single-field F-term potential. We insert our theory into the scalar-gravity part of the $SU(2,1|1)$ invariant superconformal action. That action leads us to a de Sitter solution at the inflationary trajectory. One can denote stabilization of fields in terms of the K\"ahler kinetic terms and single-field slow-roll inflation parameters. We combine these with the de Sitter swampland conjecture to generate a bounded conjecture. This approach allowed us to show that the single field slow-roll inflation works in harmony with bounded de Sitter conjecture for any concave inflation potential.
