A Neutrino Mass Matrix with Vanishing $μ$--$μ$ and $τ$--$τ$ Entries
Abstract
Description
We revisit our earlier proposal for the form of the neutrino mass matrix: a two-zero ansatz wherein the CP-violating PMNS phase $δ$ plays a surprisingly important role. We review its observable consequences and show how our ansatz follows from a softly-broken symmetry (muon number minus tau lepton number) in a see-saw model with three Higgs doublets.
