TL;DR

This paper explores large field inflation models derived from higher-dimensional gauge theories, analyzing their compatibility with CMB observations and highlighting Dante's Inferno model as the most promising within this framework.

Contribution

It introduces a framework connecting higher-dimensional gauge theories to large field inflation models and evaluates their naturalness and observational constraints.

Findings

Dante's Inferno model is most favored among analyzed models.

Constraints on gauge theory parameters from CMB data are established.

The naturalness of these models is discussed.

Abstract

Motivated by the recent detection of B-mode polarization of CMB by BICEP2 which is possibly of primordial origin, we study large field inflation models which can be obtained from higher-dimensional gauge theories. The constraints from CMB observations on the gauge theory parameters are given, and their naturalness are discussed. Among the models analyzed, Dante's Inferno model turns out to be the most preferred model in this framework.
