The (relative) size does not matter in inflation

TL;DR

This paper demonstrates that small modifications to the inflaton potential can significantly alter inflationary predictions, highlighting the sensitivity of inflation models to minor potential changes.

Contribution

It reveals that minor corrections to the inflaton potential can critically impact inflationary observables, a novel insight into inflation model sensitivity.

Findings

Tiny potential corrections can change inflationary predictions

Inflation observables are highly sensitive to small potential modifications

Highlights importance of precise potential modeling in inflation theories

Abstract

We show that a tiny correction to the inflaton potential can make critical changes in the inflationary observables for some types of inflation models.
