An Overview of Neutrino Mixing

We present a concise review of the recent important experimental developments on neutrino mixing (hints for sterile neutrinos, large θ13, possible non maximal θ23, approaching sensitivity on δCP) 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.
