A model of unified quantum chromodynamics and Yang-Mills gravity

TL;DR

This paper proposes a unified model of quantum chromodynamics and gravity using a generalized Yang-Mills framework, introducing a tensor gauge field that couples to all gluons, quarks, and anti-quarks, and reproduces classical gravitational effects.

Contribution

It introduces a novel unified gauge theory combining gravity and strong interactions via gauging space-time translations and color symmetry.

Findings

The model predicts effective metric tensors in the classical limit.

Unified gauge symmetry governs gravitational and strong interactions.

The approach aligns with experimental observations in the classical regime.

Abstract

Based on a generalized Yang-Mills framework, gravitational and strong interactions can be unified in analogy with the unification in the electroweak theory. By gauging $T(4) \times [SU(3)]_{color} $ in flat space-time, we have a unified model of chromo-gravity with a new tensor gauge field, which couples universally to all gluons, quarks and anti-quarks. The space-time translational gauge symmetry assures that all wave equations of quarks and gluons reduce to a Hamilton-Jacobi equation with the same `effective Riemann metric tensors' in the geometric-optics (or classical) limit. The emergence of effective metric tensors in the classical limit is essential for the unified model to agree with experiments. The unified model suggests that all gravitational, strong and electroweak interactions appear to be dictated by gauge symmetries in the generalized Yang-Mills framework.
