Charged gravitational instantons: extra CP violation and charge quantisation in the Standard Model

TL;DR

This paper proposes that the combination of quantum electrodynamics and quantum gravity introduces a new source of CP violation, affects chiral charge conservation, and leads to electric charge quantization, with implications for particle physics and cosmology.

Contribution

It introduces a novel mechanism linking quantum gravity and electrodynamics to CP violation and charge quantization within the Standard Model framework.

Findings

Quantum electrodynamics and gravity induce CP violation.

Chiral charge non-conservation is affected.

Electric charge becomes quantized due to this mechanism.

Abstract

We argue that quantum electrodynamics combined with quantum gravity results in a new source of CP violation, anomalous non-conservation of chiral charge and quantisation of electric charge. Further phenomenological and cosmological implications of this observation are briefly discussed within the standard model of particle physics and cosmology
