Two Majorana Neutrino Mass Doublets with Thorough Maximal Doublet Mixing from an Analogy with the K^0-Meson Oscillations
Abstract
Description
In the recent note we argued that most of the available positive and negative neutrino oscillation data can be incorporated in a four-neutrino weak interaction model with one physical condition: thorough maximal mixing of the neutrino components in each of the two mass doublets. On the level of CP-invariance an extended Pontecorvo analogy between the neutrino oscillations and the K^0-meson oscillations, which implied maximal violation of the lepton charge conservation in the neutrino mass matrix exclusively, can afford a physical clue to the three data dictated assumptions in a model with three lepton flavors and only two 4-component neutrino generations: four phenomenological neutrinos with two neutrino mass doublets, one sterile neutrino in the oscillations, and thorough maximal neutrino doublet mixing. This analogy predicts that all the four neutrino mass eigenstates are of the Majorana type.
