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 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 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 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...
