Abstract

We consider various neutrino mixing matrix parametrizations and the dependence of the mixing angles and CP-violating phase on the different parametrizations. The transformations of neutrino mixing parameters between various parametrizations are presented. Although the θ₁₃ mixing angle is determined to be small in the conventional parametrization, we note that in several other parametrizations the values of θ₁₃ are quite large. Should the value of θ₁₃ turn out to be tiny in the conventional parametrization, this study suggests that other alternative mixing matrix representations would be more suitable for dertermining the value of the CP-violating phase.
