# Asymptotically Safe Non-Minimal Inflation

## TL;DR

This paper investigates how the requirement of Asymptotic Safety constrains non-minimal inflation models, combining quantum corrections and observational data to predict large tensor-to-scalar ratios.

## Contribution

It introduces a detailed analysis of the critical surface in theory space for non-minimal inflation under Asymptotic Safety, incorporating quantum corrections beyond one loop.

## Key findings

- Severe bounds on model parameters from Planck data and theory constraints
- Prediction of a large tensor-to-scalar ratio
- Dependence of results on infrared energy scale definition

## Abstract

We study the constraints imposed by the requirement of Asymptotic Safety on a class of inflationary models with an inflaton field non-minimally coupled to the Ricci scalar. The critical surface in the space of theories is determined by the improved renormalization group flow which takes into account quantum corrections beyond the one loop approximation. The combination of constraints deriving from Planck observations and those from theory puts severe bounds on the values of the parameters of the model and predicts a quite large tensor to scalar ratio. We finally comment on the dependence of the results on the definition of the infrared energy scale which parametrises the running on the critical surface.
