Lorentz-noninvariant neutrino oscillations: model and predictions

Original · EN

We present a three-parameter neutrino-oscillation model for three flavors of massless neutrinos with Fermi-point splitting and tri-maximal mixing angles. One of these parameters is the T-violating phase ε, for which the experimental results from K2K and KamLAND appear to favor a nonzero value. In this article, we give further model predictions for neutrino oscillations. Upcoming experiments will be able to test this simple model and the general idea of Fermi-point splitting. Possible implications for proposed experiments and neutrino factories are also discussed.
