Textures for neutrino mass matrices.
We give a classification of heavy Majorana neutrino mass matrices with up to three texture zeroes, assuming the Dirac masses of the neutrinos to be of the same form as the ones of the up-quarks in the five texture zero solutions for the quark matrices. This is the case for many unified and partially unified models. We find that it is possible to have solutions which account for the solar and at...
متن کاملNeutrino mass textures from F - theory
Experimental data on the neutrino mixing and masses strongly suggest an underlying approximate symmetry of the relevant Yukawa superpotential terms. Intensive phenomenological explorations during the last decade indicate that permutation symmetries such as S4, A4 and their subgroups, under certain assumptions and vacuum alignments, predict neutrino mass textures compatible with such data. Motiv...
متن کاملA Full Determination of the Neutrino Mass Spectrum from Two-zero Textures of the Neutrino Mass Matrix
We show that it is possible to fully determine the neutrino mass spectrum from two-zero textures of the neutrino mass matrix. As a consequence, definite predictions can be obtained for the neutrinoless double beta decay. Electronic address: [email protected] Mailing address 1 In the flavor basis where the charged lepton mass matrix is diagonal, a phenomenological analysis of two-zero textu...
متن کاملLeptogenesis in Neutrino Textures with Two Zeros
The leptogenesis is studied in the neutrino textures with two zeros, which reduce the number of independent phases of the CP violation. The phenomenological favored neutrino textures with two zeros are decomposed into the Dirac neutrino mass matrix and the right-handed Majorana one in the see-saw mechanism. Putting the condition to suppress the μ → eγ decay enough, the texture zeros of the Dira...
متن کاملNeutrino Mass Textures from Oscillations with Maximal Mixing
We study the implications of neutrino oscillations with maximal mixing for the neutrino Dirac and Majorana matrices in the see-saw mechanism for three non degenerate neutrino masses. We find the form of the Dirac matrix for a structure-less Majorana matrix and, conversely, the structure of the Majorana matrix if the Dirac matrix is according to our naive intuition. We give some examples of Majo...
