Tripartite 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...
متن کاملNatural Neutrino Mass Matrix
Naturalness of the neutrino mass hierarchy and mixing is studied. First we select among 12 neutrino mixing patterns a few patterns, which could form the natural neutrino mass matrix. Further we show that if the Dirac neutrino mass matrix is taken as the natural one in the quark sector, then only two mixing patterns without the large mixing lead to the natural right-handed Majorana mass matrix. ...
متن کاملNeutrino Mass Matrix with Approximate Flavor Symmetry
Phenomenological implications of neutrino oscillations implied by recent experimental data on pattern of neutrino mass matrix are diss-cussed. It is shown that it is possible to have a neutrino mass matrix which shows approximate flavor symmetry; the neutrino mass differences arise from flavor violation in off-diagonal Yukawa couplings. Two modest extensions of the standard model, which can emb...
متن کاملComment on Radiative Neutrino Mass Matrix with a Sterile Neutrino
New era of physics beyond the standard quark-lepton physics has been opened by the SuperKamiokande collaboration who has provided the convincing evidence on atmospheric neutrino oscillations. [1] There have also been other observed anomalous phenomena suggesting that neutrinos are oscillating, which are often referred to the solar neutrino deficit [2] and to the LSND signal [3]. Such neutrino o...
