TL;DR

This paper proposes a gauge theory of gravity that incorporates massive gravitons while maintaining local gauge invariance, suggesting these massive particles could explain dark energy and dark matter.

Contribution

It introduces a novel gauge model with massive gravitons that preserves local gauge symmetry, expanding the theoretical framework of quantum gravity.

Findings

Massive gravitons can exist without breaking gauge symmetry.

The model provides a potential explanation for dark energy and dark matter.

The theory remains perturbatively renormalizable.

Abstract

Gauge theory of gravity is formulated based on principle of local gauge invariance. Because the model has strict local gravitational gauge symmetry, gauge theory of gravity is a perturbatively renormalizable quantum model. However, in the original model, all gauge gravitons are massless. We want to ask that whether there exists massive gravitons in Nature? In this paper, we will propose a gauge model with massive gravitons. The mass term of gravitational gauge field is introduced into the theory without violating the strict local gravitational gauge symmetry. Massive gravitons can be considered to be possible origin of dark energy and dark matter in the Universe.
