# Renormalizable SU(5) Unification

@article{Prez2016RenormalizableSU, title={Renormalizable SU(5) Unification}, author={Pavel Fileviez P{\'e}rez and Clara Murgui}, journal={Physical Review D}, year={2016}, volume={94}, pages={075014} }

We propose a simple renormalizable grand unified theory based on the SU(5) gauge symmetry where the neutrino masses are generated at the quantum level through the Zee mechanism. In this model the same Higgs needed to correct the mass relation between charged leptons and down-type quarks plays a crucial role in generating neutrino masses. We show that in this model one can satisfy the constraints coming from the unification of gauge couplings and the mechanism for neutrino masses is discussed in…
