Universal regular short distance behavior from an interaction with a scale invariant gravity

TL;DR

This paper proposes that assuming scale invariance in four-dimensional quantum gravity leads to a universal and more regular behavior of quantum field correlations at short distances.

Contribution

It introduces a simple scaling argument demonstrating the universal short-distance behavior of quantum fields interacting with scale-invariant gravity.

Findings

Correlation functions exhibit more regular behavior at short distances.

Scale invariance in quantum gravity implies universal short-distance properties.

Abstract

We assume that the fourdimensional quantum gravity is scale invariant at short distances. We show through a simple scaling argument that correlation functions of quantum fields interacting with gravity have a universal (more regular) short distance behavior.
