Inflation from Strongly Coupled Gauge Dynamics

TL;DR

This paper proposes that strongly coupled gauge theories, modeled holographically, can produce a viable small-field inflation potential, addressing tuning issues and the eta problem within a single inflaton framework.

Contribution

It introduces a holographic approach to generate inflationary potentials from strongly coupled gauge dynamics, providing a novel link between gauge theories and inflation model building.

Findings

Holographic models can produce suitable inflation potentials.

Tuning conditions in the gauge sector are identified.

The eta problem can be addressed within this framework.

Abstract

We argue, using a phenomenological holographic approach, that walking, strongly coupled gauge theories generate a suitable potential for a small field inflation model. We show that the effective description is a model of a single inflaton. We determine the tunings necessary in the gauge sector to generate inflation and overcome the \eta problem.
