Gauge Theory of Gravity Requires Massive Torsion Field

TL;DR

This paper argues that a gauge theory of gravity should include a massive torsion field, with the torsion gauge boson likely having a rest mass at the Planck scale, to advance quantum gravity models.

Contribution

It provides theoretical arguments supporting a massive torsion field in gauge theories of gravity, proposing the Planck mass as the gauge boson mass.

Findings

Massive torsion field is favored over massless models.

The torsion gauge boson likely has a rest mass at the Planck scale.

Supports unification of quantum theory and gravity through gauge theory.

Abstract

One of the greatest unsolved issues of the physics of this century is to find a quantum field theory of gravity. According to a vast amount of literature unification of quantum field theory and gravitation requires a gauge theory of gravity which includes torsion and an associated spin field. Various models including either massive or massless torsion fields have been suggested. We present arguments for a massive torsion field, where the probable rest mass of the corresponding spin three gauge boson is the Planck mass.
