An $A_5$ inverse seesaw model with perturbed golden ratio mixing

Abstract

We propose a theory based on the $A_5$ discrete group which successfully accounts for lepton masses and mixings. In the proposed model, the neutrino masses arise from an inverse seesaw mechanism. The leptonic mixing consists in a perturbed golden ratio mixing pattern with a strong correlation arising between the leptonic mixing observables, which can be expressed as ${\theta }_{13}$ predicting the other mixing angles and the Dirac CP phase.
