Abstract

We propose for the flavour structure of both the quark and lepton sectors, the principle of Universal Democracy (UD), which reflects the presence of a Z3Z_3 symmetry. In the quark sector, we emphasize the importance of UD for obtaining small mixing and flavour alignment, while in the lepton sector, large mixing, including the recently measured value of Ue3U_{e3}, is obtained in the UD framework through the seesaw mechanism. An interesting correlation between the values of Ue3U_{e3} and sin2(θ23)\sin^2(\theta_{23}) is pointed out, with the prediction of sin2(θ23)0.42\sin^2(\theta_{23})\approx 0.42 in the region where Ue3U_{e3} is in agreement with the DAYA-BAY experiment.
