Neutrino mixing in Seesaw model
We study the neutrino mixing matrix (MNS matrix) in seesaw model. Assuming large mass hierarchy for heavy right-handed Majorana mass, we show that MNS matrix is determined by a unitary matrix which transforms neutrino yukawa term into a triangular form. Large mixing may occur even if yukawa matrix for charged lepton and that for neutrino is simultaneously diagonalized by biunitary transformatio...
متن کاملNeutrino mixing in the seesaw model
In the seesaw model with hierarchical Dirac masses, the neutrino mixing angle exhibits the behavior of a narrow resonance. In general, the angle is strongly suppressed, but it can be maximal for special parameter values. We delineate the small regions in which this happens, for the two flavor problem. On the other hand, the physical neutrino masses are hierarchical, in general, except in a larg...
متن کاملMinimal Modification To The Tri-bimaximal Neutrino Mixing
Abstract Current experimental data on neutrino oscillations are consistent with the tri-bimaximal mixing. If future experimental data will determine a non-zero Ve3 and/or find CP violations in neutrino oscillations, there is the need to modify the mixing pattern. We find that a simple neutrino mass matrix, resulting from A4 family symmetry breaking with residual Z3 and Z2 discrete symmetries re...
متن کاملRenormalization Effect on Large Neutrino Flavor Mixing in the Minimal Supersymmetric Standard Model
In the minimal supersymmetric standard model, we have studied the evolution of the neutrino flavor mixing by using the renormalization group equation(RGE) with the Georgi-Jarlskog texture for the Yukawa coupling matrices. For the large Yukawa coupling of the charged lepton, i.e., tanβ ≫ 1, the neutrino flavor mixing increases significantly with running down to the electroweak scale by the RGE. ...
متن کاملRadiative Corrections to Neutrino Mixing and CP Violation in the Minimal Seesaw Model with Leptogenesis
Radiative corrections to neutrino mixing and CP violation are analyzed in the minimal seesaw model with two heavy right-handed neutrinos. We find that textures of the effective Majorana neutrino mass matrix are essentially stable against renormalization effects. Taking account of the Frampton-GlashowYanagida ansatz for the Dirac neutrino Yukawa coupling matrix, we calculate the running effects ...
