Neutrino Mass Matrix with Two Zeros and Leptogenesis
The leptogenesis is studied in the neutrino mass matrix with two zeros, which reduces the number of independent phases of the CP violation. These texture zeros are decomposed into the Dirac neutrino mass matrix and the right-handed Majorana one in the see-saw mechanism. It is found that there are six textures for the Dirac neutrino mass matrix, among which one texture with three zeros has three...
متن کاملPrediction of Ue3 in Neutrino Mass Matrix with Two Zeros
We have discussed predictions of |Ue3| and JCP in the framework of the neutrino mass matrix with two zeros. In the case of the best fit values of tan θ12, tan 2 θ23, ∆m 2 sun and ∆m atm , the prediction of |Ue3| is 0.11 ∼ 0.14. The lower bound of |Ue3| is 0.05, which depends on tan θ12 and tan θ23. We have investigated the stability of these predictions taking account of small corrections to ze...
متن کاملStability of Predictions in Neutrino Mass Matrix with Two Zeros
We have discussed predictions of |Ue3| and JCP in the framework of the neutrino mass matrix with two zeros. The lower bound of |Ue3| is 0.05, which depends on tan θ12 and tan θ23. We have investigated the stability of these predictions taking account of small corrections to zeros, which may come from radiative corrections or off-diagonal elements of the charged lepton mass matrix. The lower bou...
متن کاملSimple radiative neutrino mass matrix for solar and atmospheric oscillations.
A simple 3× 3 neutrino Majorana mass matrix is proposed to accommodate both the solar and atmospheric neutrino deficits. This scenario can be realized naturally by a radiative mechanism for the generation of neutrino masses. It also goes together naturally with electroweak baryogenesis and cold dark matter in a specific model. There is now a good deal of evidence from different experiments that...
متن کاملTripartite Neutrino Mass Matrix
The 3 × 3 Majorana neutrino mass matrix is written as a sum of 3 terms, i.e. Mν = MA +MB +MC , where MA is proportional to the identity matrix and MB,C are invariant under different Z3 transformations. This Mν is very suitable for understanding atmospheric and solar neutrino oscillations, with sin 2θatm and tan 2 θsol fixed at 1 and 0.5 respectively, in excellent agreement with present data. It...
