An Overview of Neutrino Mixing

Abstract

We present a concise review of the recent important experimental developments on neutrino mixing (hints for sterile neutrinos, large ${\theta }_{13}$, possible non maximal ${\theta }_{23}$, approaching sensitivity on ${\delta }_{CP}$) and their implications on models of neutrino mixing. The new data disfavour many models but the surviving ones still span a wide range going from Anarchy (no structure, no symmetry in the lepton sector) to a maximum of symmetry, as for the models based on discrete non-abelian flavour groups.
