Degenerate Dirac Neutrinos
A simple extension of the standard model is proposed in which all the three generations of neutrinos are Dirac particles and are naturally light. We then assume that the neutrino mass matrix is diagonal and degenerate, with a few eV mass to solve the dark matter problem. The self energy radiative corrections, however, remove this degeneracy and allow mixing of these neutrinos. The electroweak r...
متن کامل(Pseudo)-Dirac neutrinos and leptogenesis
We discuss how Dirac neutrinos can naturally be generated in supersymmetry and how they allow for an Affleck-Dine leptogenesis scenario, in which a leftright asymmetry is generated in the sneutrino sector, the left part of which is transferred to a baryon asymmetry via sphaleron transitions. No exotic fields need to be added to the MSSM other than the right-handed neutrino.
متن کاملPseudo-Dirac Solar Neutrinos
Three of the four viable solutions of the solar neutrino problem are consistent with close to maximal leptonic mixing: sin θ12 = 1 2(1 − ǫ) with |ǫ| ≪ 1. Theoretical models can naturally explain such a situation if approximate horizontal symmetries force a pseudoDirac structure on the neutrino mass matrix. An experimental determination of |ǫ| and sign(ǫ) will constrain the structure of the neut...
متن کاملRevisiting pseudo-Dirac neutrinos
We study the pseudo-Dirac mixing of left and right-handed neutrinos in the case where the Majorana masses ML and MR are small when compared with the Dirac mass, MD. The light Majorana masses could be generated by a non-renormalizable operator reflecting effects of new physics at some high energy scale. In this context, we obtain a simple model independent ∗[email protected] †a...
متن کاملPseudo-Dirac Neutrinos
We propose a scheme in which a pseudo-Dirac structure for three family of light neutrinos is generated naturally. An extended Higgs sector with a majoron is used for the generation of the leptonic number violating neutrino Majorana mass. The resultant neutrino mass matrix could easily fit all available experimental data. We discuss relevant constraints on the scales involved for the model to be...
