Higgs Mass Spectrum in non-SUSY SU(5)

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.
