Gauge federation as an alternative to unification

TL;DR

This paper explores the idea that extra independent SU(N) gauge groups could exist separately from the Standard Model, examining their coupling behaviors and potential TeV-scale physics implications as an alternative to traditional unification.

Contribution

It introduces the concept of gauge federation, analyzing the running of coupling constants for independent SU(N) groups as a novel approach to gauge theory unification.

Findings

Coupling constants suggest possible common origins of gauge groups.

Multiple models indicate physics at the TeV scale.

Gauge federation offers an alternative to grand unification.

Abstract

We motivate and explore the possibility that extra SU(N) gauge groups may exist independently of the Standard Model groups, yet not be subgroups of some grand unified group. We study the running of the coupling constants as a potential evidence for a common origin of all the gauge theories. Several different example are displayed. Some of the multiple options involve physics at the TeV scale.
