Abstract

Possible alternatives to tri-bimaximal mixing are presented based on other symmetry principles, and their predictions for |U_e3|, sin² theta₁₂ and sin² theta₂₃ are compared to the present neutrino mixing data. In some cases perturbations are required to give better agreement with the data, and the use of a minimal approach is illustrated. Precise experimental determinations of the mixing parameters will be required to decipher the correct mixing pattern and to pin down the appropriate flavor symmetry.
