Can leptonic mixing matrix have a Wolfenstein form?

We analyze the possibility of leptonic mixing matrix having a Wolfenstein form at Grand Unified Theory scale. The renormalization group evolution masses and angles from high scale to electroweak scale, in certain new physics scenarios, can significantly alter matrix. In past it was shown that such significant enhancement implies be same or similar structure quark one. thoroughly this hypothesis light latest neutrino oscillation data as well other constraints those coming neutrinoless double beta decay. show an ansatz, least within context minimal supersymmetric models, is no longer compatible with experimental data.
