Unity of elementary particles and forces for the third family

TL;DR

This paper introduces a non-supersymmetric SU(5) model unifying only the third fermion family, addressing coupling unification issues, baryon asymmetry, and predicting TeV-scale leptoquark signatures for collider searches.

Contribution

It presents a novel SU(5) model that unifies only the third family and explains baryon asymmetry, with testable predictions at the LHC.

Findings

Couplings unify at the TeV scale in the model.

Leptoquark gauge bosons can be detected as resonances at the LHC.

Model provides a mechanism for baryon number violation.

Abstract

We propose a non-supersymmetric SU(5) model in which only the third family of fermions are unified. The model remedies the non-unification of the three Standard Model couplings in non-supersymmetric SU(5). It also provides a mechanism for baryon number violation which is needed for the baryon asymmetry of the Universe and is not present in the Standard Model. Current experimental constraints on the leptoquark gauge bosons, mediating such baryon and lepton violating interactions in our model, allow their masses to be at the TeV scale. These can be searched for as a (b\tau) or (tt) resonance at the Large Hadron Collider as predicted in our model.
