Higgs Mass Spectrum in non-SUSY SU(5)

TL;DR

This paper analyzes the Higgs mass spectrum in non-supersymmetric SU(5) GUTs, identifying naturally light multiplets that could be detected at the LHC, thereby linking neutrino masses, unification, and proton decay.

Contribution

It provides a detailed study of the Higgs mass spectrum in non-SUSY SU(5) models and identifies light multiplets accessible at current collider energies.

Findings

Identification of naturally light multiplets within LHC reach

Connection between neutrino masses and unification in SU(5) models

Implications for proton decay experiments

Abstract

Non-supersymmetric grand unified theories based on SU(5) have had a revival during the past years. This is mainly due to their ability to connect neutrino masses with unification and proton decay. In that way they provide a framework for testable models at coming experiments. We study the mass spectrum of such models and determine naturally light multiplets within the LHC reach.
