General Relativity in noncommutative spacetime as a unified framework for all interactions and the Higgs field

TL;DR

This paper develops a unified framework combining General Relativity and particle interactions within a noncommutative spacetime, deriving all known forces and the Higgs field from gravity with minimal parameters.

Contribution

It introduces a novel noncommutative spacetime model incorporating new fermions, unifying all interactions and the Higgs field as gravitational components.

Findings

Finite physical spectrum achieved

All known interactions derived from gravity

Only four free parameters used

Abstract

General Relativity in the noncommutative spacetime of ${\cal M}^4 \times Z_2 \times Z_2$ is constructed based on a new type of fermions in addition to the known chiral quark-leptons. While this theory has a finite physical spectrum, all the known interactions of Nature and Higgs fields can be derived from it as components of gravity with only four free parameters.
