Solar and Atmospheric Neutrino Oscillations
I review the status of neutrino masses and mixings in the light of the solar and atmospheric neutrino data in the framework of two–, three– and four neutrino mixing. 1 Indications for Neutrino Mass: Two–Neutrino Analysis I a first review the present experimental status for solar and atmospheric neutrinos and the results of the different analysis in the framework of two–neutrino oscillations. Th...
متن کاملDecoupling of solar and atmospheric neutrino oscillations
The scheme of mixing of three neutrinos with a mass hierarchy is considered for the explanation of the solar and atmospheric neutrino problems through neutrino oscillations. It is shown that the recent results of the CHOOZ experiment imply that the element Ue3 of the neutrino mixing matrix is small, that the oscillations of solar neutrinos are described by the two-generation formalism and that ...
متن کاملSolar and Atmospheric Four–Neutrino Oscillations
We present an analysis of the neutrino oscillation solutions of the solar and atmospheric neutrino problems in the framework of four–neutrino mixing where a sterile neutrino is added to the three standard ones and the mass spectra presents two separated doublets. Such scenarios allow for simultaneous transitions of solar νe, as well as atmospheric νμ, into active and sterile neutrinos controlle...
متن کاملSolar and Atmospheric Neutrino Oscillations from Bilinear R-Parity Violation
We discuss general predictions for neutrino masses and mixing angles from R parity violation in the Minimal Supersymmetric Standard Model. If the soft supersymmetry breaking terms are flavor blind at short distance, then the leptonic analogue of the CKM matrix depends on only two real parameters, which are completely determined by fits to solar and atmospheric neutrino oscillations. Either the ...
متن کاملA See-Saw Model for Atmospheric and Solar Neutrino Oscillations
We have constructed an explicit see-saw model containing two singlet neutrinos, one carrying a (B − 3Le) gauge charge with an intermediate mass scale of ∼ O(10) GeV along with a sterile one near the GUT (grand unification theory) scale of ∼ O(10) GeV. With these mass scales and a reasonable range of Yukawa couplings, the model can naturally account for the near-maximal mixing of atmospheric neu...
