Quantum gravity at a TeV and the renormalization of Newton's constant

TL;DR

This paper explores the possibility that quantum gravity effects could lower the scale of quantum gravity to the TeV range through renormalization of Newton's constant, without extra dimensions, and discusses experimental signatures like small black hole production.

Contribution

It introduces a model where renormalization effects significantly alter Newton's constant, potentially reducing the quantum gravity scale to TeV energies without extra dimensions.

Findings

Renormalization can dramatically change Newton's constant at high energies.

Small black holes could be produced at TeV scales as experimental signatures.

The model suggests new avenues for detecting quantum gravity effects.

Abstract

We examine whether renormalization effects can cause Newton's constant to change dramatically with energy, perhaps even reducing the scale of quantum gravity to the TeV region without the introduction of extra dimensions. We examine a model that realizes this possibility and describe experimental signatures from production of small black holes.
