چکیده

The most plausible see-saw explanation of the smallness of the neutrino masses is based on the assumption that total lepton number is violated at a large scale and neutrinos with definite masses are Majorana particles. In this review we consider in details difference between Dirac and Majorana neutrino mixing and possibilities to reveal Majorana nature of neutrinos with definite masses.

Nearly Tri-bimaximal Neutrino Mixing and CP Violation from μ-τ Symmetry Breaking

Assuming the Majorana nature of massive neutrinos, we generalize the Friedberg-Lee neutrino mass model to include CP violation in the neutrino mass matrix Mν . We show that a favorable neutrino mixing pattern (with θ12 ≈ 35.3, θ23 = 45, θ13 6= 0 and δ = 90) can naturally be derived from Mν , if it has an approximate or softly-broken μ-τ symmetry. We point out a different way to obtain the nearl...

On the indistinguishibility of Majorana- from Dirac-neutrino propagation in a stellar medium

We study, in the framework of the Standard Model, the propagation of (pure) Majorana neutrinos in a typical stellar medium and show that Majorana neutrino matter oscillations are completely indistinguishable from Dirac ones, even if in the case of no family mixing Majorana neutrinos can be distinguished from Dirac ones in the non-relativistic limit. Moreover, if CP violation is present, an effe...

Hierarchical Majorana Scales in the Seesaw Model

If the mixing angles in each of the seesaw sectors are all small, and the neutrino masses are hierarchical, we study the conditions for large neutrino mixing using triangular matrices. In particular, the implication of the neutrino oscillation data for the mass hierarchy in the heavy Majorana sector is examined, and the heavy Majorana scales are shown to depend sensitively on the solar mixing a...

Neutrino 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...

Phenomenological analysis of properties of the RH Majorana neutrino in the seesaw mechanism

As an extension of our previous work in the seesaw mechanism, we analyze the influence of Ue3 on the properties (masses and mixing) of the RH Majorana neutrinos in three flavors. The quasidegenerate light neutrinos case is also considered. Assuming the hierarchical Dirac neutrino masses, we find the heavy Majorana neutrino mass spectrum is either hierarchical or partial degenerate if θ 23 is la...
