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 $S3_l \times S3_ν$. Our "best guess" for the smallest neutrino mixing angle remains: $\sin θ_{13}=\sqrt{2 Δm^2_{sol}/(3 Δm^2_{atm})} \simeq 0.13$.

16 pages latex. Written version of a talk presented by W. G. Scott at "Neutrino Telescopes", Venice, Italy, 10-13 March 2009 (to be published in the proceedings). Version-2 incorporates some minor re-wordings and additional references. Version-3/Version-4 correct a misquote in Eq. 19 of the expression for F in terms of mass-matrix anti-commutators
