Using the fact that the neutrino mixing matrix U = (UeU nu)-U-dagger, where U-e and U-nu result from the diagonalization of the charged lepton and neutrino mass matrices, we analyze the predictions based on the sum rules which the Dirac phase delta present in U satisfies when U-nu has a form dictated by, or associated with, discrete flavor symmetries and U-e has a "minimal" form (in terms of angles and phases it contains) that can provide the requisite corrections to U-nu, so that the reactor, atmospheric and solar neutrino mixing angles theta(13), theta(23) and theta(12) have values compatible with the current data.

Abstract
Using the fact that the neutrino mixing matrix U = (UeU nu)-U-dagger, where U-e and U-nu result from the diagonalization of the charged lepton and neutrino mass matrices, we analyze the predictions based on the sum rules which the Dirac phase delta present in U satisfies when U-nu has a form dictated by, or associated with, discrete flavor symmetries and U-e has a "minimal" form (in terms of angles and phases it contains) that can provide the requisite corrections to U-nu, so that the reactor, atmospheric and solar neutrino mixing angles theta(13), theta(23) and theta(12) have values compatible with the current data.
