Lepton masses and mixings in nonminimal renormalizable SUSY SO(10)

By Michal Malinsky, SISSA, Trieste, Italy

A simple predictive extension of the minimal renormalizable SUSY SO(10) is studied. The decoupling features of the considered additional 120-dimensional Higgs multiplet allow for perturbative estimation of the effect beyond the minimal SUSY SO(10). The model accomodates a completely realistic spectrum of fermion masses and predicts the PMNS mixing angles in agreement with the latest neutrino data.
