Family hierarchy and large neutrino mixings

Fu-Sin Ling, Pierre Ramond

The recent neutrino data seem to favor two large and one small mixing angles and a hierarchy of their squared mass differences. We discuss these within the context of hierarchical neutrino masses. We show that this scheme suggests a specific neutrino mass matrix with mild fine-tuning. We then present a Froggatt-Nielsen model that reproduces this matrix.
