Predictions for the Leptonic Dirac CP-Violating Phase

We explore the effects of correlations among observable parameters of neutrino mixing on predictions for the leptonic Dirac CP-violating phase. We focus on a standard class of theoretical models that include a single source of CP-violation due to charged lepton corrections. We take two complementary approaches -- one in which the model parameters are uncorrelated and one in which correlations are introduced as a way to optimally reproduce the experimentally measured mixing angles. We find that in both cases we can guarantee a physically meaningful prediction for the most likely value of the leptonic Dirac CP-violating phase.
