Fully Constrained Majorana Neutrino Mass Matrices Using
R. Krishnan, P. F. Harrison, W. G. Scott
In 2002, two neutrino mixing ansatze having trimaximally-mixed middle () columns, namely tri-chi-maximal mixing () and tri-phi-maximal mixing ($\text{T}ϕ\te…
The SU(3) Algebra in a Cyclic Basis
P. F. Harrison, R. Krishnan, W. G. Scott
With the couplings between the eight gluons constrained by the structure constants of the su(3) algebra in QCD, one would expect that there should exist a special basis (or set of…
Deviations from Tribimaximal Neutrino Mixing using a Model with Symmetry
P. F. Harrison, R. Krishnan, W. G. Scott
We present a model of neutrino mixing based on the flavour group in order to account for the observation of a non-zero reactor mixing angle (). The model provides a…
Simplest Neutrino Mixing from S4 Symmetry
R. Krishnan, P. F. Harrison, W. G. Scott
In 2004, two of us proposed a texture, the "Simplest" neutrino mass matrix, which predicted sin(theta13)=sqrt((2 Solar-Delta m^2)/(3 Atm-Delta m^2)) and delta_CP=90 degrees. Using…
Exact One-Loop Evolution Invariants in the Standard Model
P. F. Harrison, R. Krishnan, W. G. Scott
Guided by considerations of flavour symmetry, we construct a set of exact Standard Model (SM) renormalisation group evolution invariants which link quark masses and mixing paramete…
A Flavour-Symmetric Perspective on Neutrino Mixing
P. F. Harrison, W. G. Scott
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 Fl…
