Quantum gravitational contributions to quantum electrodynamics

TL;DR

This paper demonstrates that quantum gravity induces quadratic energy-dependent corrections to quantum electrodynamics, leading to a reduction of electric charge at high energies, supporting the concept of asymptotic freedom.

Contribution

It provides a controversy-free analysis showing quantum gravity effects cause charge to decrease at high energies, a novel insight into quantum electrodynamics and gravity interactions.

Findings

Quantum gravity corrections are quadratic in energy.

Electric charge decreases at high energies.

Supports asymptotic freedom in quantum electrodynamics.

Abstract

Quantum electrodynamics describes the interactions of electrons and photons. Electric charge (the gauge coupling constant) is energy dependent, and there is a previous claim that charge is affected by gravity (described by general relativity) with the implication that the charge is reduced at high energies. But that claim has been very controversial with the situation inconclusive. Here I report an analysis (free from earlier controversies) demonstrating that that quantum gravity corrections to quantum electrodynamics have a quadratic energy dependence that result in the reduction of the electric charge at high energies, a result known as asymptotic freedom.
