# Forces on a Clifford bundle

## TL;DR

This paper explores the fundamental forces compatible with a Clifford bundle framework over spacetime, extending the geometric approach used for Dirac and Einstein equations to include other forces.

## Contribution

It explicitly enumerates the fundamental forces permissible within the Clifford bundle geometric framework, expanding the understanding of force incorporation in this setting.

## Key findings

- Enumerates fundamental forces compatible with Clifford bundle framework
- Extends geometric approach to include additional forces beyond gravity and electromagnetism
- Provides a basis for further unification of forces in geometric models

## Abstract

In a companion article, the Clifford bundle over spacetime was used as a geometric framework for obtaining coupled Dirac and Einstein equations. Other forces may be incorporated using minimal coupling. Here the fundamental forces that are allowed within this framework are explicitly enumerated.
