The Neutrino Mass Matrix - From A4 to Z3
Ernest Ma
Abstract
With the recent experimental advance in our precise knowledge of the neutrino oscillation parameters, the correct form of the 3 X 3 neutrino mass matrix is now approximately known. I discuss how this may be obtained from symmetry principles, using as examples the finite groups A4 and Z3, in two complete theories of leptons (and quarks).
