Low Scale Unification of Gauge Interactions

TL;DR

This paper explores the potential for unifying Standard Model gauge interactions at a low energy scale within four-dimensional theories, ensuring proton stability and aligning with experimental data.

Contribution

It introduces a minimal theory with local baryon and lepton numbers that achieves low-scale unification consistent with experiments.

Findings

Proton remains stable in the proposed scenarios

Unification occurs at a low energy scale compatible with observations

Implications for cosmology are briefly discussed

Abstract

We investigate the possibility to realize the unification of the Standard Model gauge interactions at the low scale in four dimensions. We find that the fields needed to define a minimal theory where baryon and lepton numbers are local symmetries, allow for unification at the low scale in agreement with experiments. In these scenarios the proton is stable and we briefly discuss the implications for cosmology.
