# Scale-invariant inflation with one-loop quantum corrections

## TL;DR

This paper investigates quantum corrections to a classically scale-invariant inflationary model, demonstrating how one-loop effects influence inflation dynamics and lead to the emergence of a fundamental mass scale.

## Contribution

It provides a detailed analysis of one-loop quantum corrections in a scale-invariant inflationary model, combining analytical and numerical methods to understand their impact.

## Key findings

- Quantum corrections affect the inflationary potential near the unstable point.
- The model naturally generates a fundamental mass scale after symmetry breaking.
- One-loop effects modify the classical inflationary dynamics.

## Abstract

We study quantum corrections to an inflationary model, which has the attractive feature of being classically scale-invariant. In this model, quadratic gravity plays along a scalar field in such a way that inflation begins near the unstable point of the effective potential and it ends at a stable fixed point, where the scale symmetry is broken and a fundamental mass scale naturally emerges. We compute the one loop corrections to the classical action on the curved background of the model and we report their effects on the classical dynamics with both analytical and numerical methods.
