Neutrino masses generation in a Z(4) model

Aranda, Alfredo; Bonilla, Cesar; Rojas, Alma D.


We present a renormalizable flavor model with Z(4) as flavor symmetry in both the quark and lepton sectors. The model is constructed with a minimal approach and no right-handed neutrinos are introduced. In this approach a minimum number of two SU(2) Higgs doublets and one scalar singlet are required in order to obtain the Nearest Neighbor Interaction form for charged fermions and to generate neutrino masses radiatively. For the quark sector we follow the charge assignations made by Branco et al. in reference [ G. C. Branco, D. Emmanuel-Costa, and C. Simoes, Phys. Lett. B 690, 62 (2010).]. All fermion masses and mixing angles in the model are in agreement with current experimental data and only the inverted hierarchy for the neutrino mass spectrum is allowed. Since neutrinos are Majorana the contribution to neutrinoless double beta decay is also analyzed.
