Minimal gauge inflation and the refined Swampland conjecture

TL;DR

This paper develops a method to analyze minimal gauge inflation models against the refined Swampland conjecture, identifying parameter spaces consistent with quantum gravity constraints and observational data.

Contribution

It introduces a generic approach to test inflationary potentials with inflection points against the refined dS conjecture, applying it to minimal gauge inflation.

Findings

Identified parameter regions where minimal gauge inflation is consistent with the Swampland criteria.

Demonstrated compatibility of the model with latest observational data.

Provided a framework applicable to similar inflationary models.

Abstract

The refined de Sitter (dS) conjecture provides two consistency conditions for an effective theory potential of a quantum gravity theory. Any inflationary model can be checked by these conditions and minimal gauge inflation is not an exception. We develop a generic method to analyze a monotonically growing potential with an inflection point on the way to the plateau near the top such as the potential in minimal gauge inflation model and the Higgs inflation. Taking the latest observational data into account, we find the fully consistent parameter space where the model resides in the Landscape rather than in the Swampland.
