Predictions of Neutrino Mixing Angles in a T'Model

Abstract

Flavor symmetry ($T^{{}^{\prime }}\times Z_2$) where $T^{{}^{\prime }}$ is the binary tetrahedral group predicts for neutrino mixing angles ${\theta }_{13}=\sqrt{2}(\frac{\pi }{4}-{\theta }_{23})$ and, with one phenomenological input, provides upper and lower bounds on both ${\theta }_{13}$ and ${\theta }_{23}$. The predictions arise from the deviation of the Cabibbo angle ${\Theta }_{12}$ from its lowest-order value $\tan 2{\Theta }_{12}=(\sqrt{2})/3$ and from the $T^{{}^{\prime }}$ mechanism which relates mixing of $({\nu }_{\tau },{\nu }_{\mu },{\nu }_e)$ neutrinos to mixing of $(s,d)$ quarks.
