Description
The unification of gauge and top Yukawa couplings is an attractive feature of gauge-Higgs unification models in extra dimensions. It is usually considered difficult to obtain based on simple group theory analyses. We reconsider the most minimal realisation including the renormalisation group running at one loop. Our results show that the model is reconciled with the low energy values of the couplings in the standard model without introducing any extra ingredients. We thus achieve, for the first time, a genuine unification of gauge and Yukawa couplings.
