# Pure Natural Inflation

## TL;DR

This paper proposes a simple inflation model where an axionic inflaton coupled to pure Yang-Mills theory can produce observationally consistent scalar spectral index and tensor-to-scalar ratio.

## Contribution

It introduces a novel inflationary scenario involving axionic inflaton and pure Yang-Mills coupling that aligns with current cosmological observations.

## Key findings

- Model matches observed n_s and r values
- Provides a new theoretical framework for inflation
- Suggests axionic fields as viable inflaton candidates

## Abstract

We point out that a simple inflationary model in which the axionic inflaton couples to a pure Yang-Mills theory may give the scalar spectral index (n_s) and tensor-to-scalar ratio (r) in complete agreement with the current observational data.
