Probing Quark-Lepton Unification with Leptoquark and Higgs Decays

TL;DR

This paper explores how decay patterns of leptoquarks and Higgs bosons can serve as tests for quark-lepton unification theories at the TeV scale, highlighting specific decay relations predicted by minimal models.

Contribution

It identifies unique decay width relations between leptoquarks and Higgs bosons that can experimentally test quark-lepton unification at the TeV scale.

Findings

Decay widths of leptoquarks and Higgs bosons are related by the unification symmetry.

Minimal quark-lepton unification models predict specific decay relations.

These relations can be used to experimentally verify the unification hypothesis.

Abstract

We point out unique relations between the decay widths for leptoquarks and Higgs bosons that can be used to test the unification of quarks and leptons at the TeV scale. We discuss the main predictions of the minimal theory for quark-lepton unification and show how the different decays for leptoquarks and Higgses are related by the symmetry of the theory.
