# Towards implications of asymptotically safe gravity for particle physics

## TL;DR

This paper explores how asymptotically safe gravity could influence particle physics by potentially making the Standard Model UV complete and enabling calculations of some couplings, with implications for quark mass differences.

## Contribution

It discusses the possibility that quantum gravity effects induce an asymptotically safe fixed point for the Standard Model, offering a new approach to predict Standard Model parameters.

## Key findings

- Potential for the Standard Model to be UV complete due to quantum gravity effects
- Possibility to calculate some Standard Model couplings from the fixed point
- Explanation of the top-bottom quark mass difference through the fixed point

## Abstract

We review aspects of the interplay of asymptotically safe gravity with matter, focusing on the potential predictive power of the quantum scale-symmetry underlying the asymptotically safe fixed point. We explain how an asymptotically safe fixed point for the Standard Model, induced by quantum-gravity fluctuations, might i) render the Standard Model ultraviolet complete and ii) allow us to calculate the values of some of the Standard-Model couplings. In particular, we highlight that such a fixed point might explain the mass-difference between the top and bottom quark.
