New mixing pattern for neutrinos

Abstract

We propose a new mixing pattern for neutrinos with a nonzero mixing angle $θ_{13}$. Under a simple form, it agrees well with current neutrino oscillation data and displays a number of intriguing features including the $μ$-$τ$ interchange symmetry $|U_{μi}|=|U_{τi}|$, $(i=1,2,3)$, the trimaximal mixing $|U_{\e 2}|=|U_{μ2}|=|U_{τ2}|=1/\sqrt{3}$, the self-complementarity relation $θ_1+θ_3=45°$, together with the maximal Dirac CP violation as a prediction.
