A Flavour-Symmetric Perspective on Neutrino Mixing

Abstract

A review and consolidation of some of our more recent publications, many with our various collaborators. While we cannot resist mentioning Tribimaximal mixing, our main theme is Flavour Symmetry, in particular Flavour-Symmetric Observables, scalar (or pseudo-scalar) under $S3_l \times S3_{\nu}$. Our "best guess" for the smallest neutrino mixing angle remains: $\sin \theta_{13}=\sqrt{2 \Delta m^2_{sol}/(3 \Delta m^2_{atm})} \simeq 0.13$.
