Neutrino decay confronts the SNO data
We investigate the status of the neutrino decay solution to the solar neutrino problem in the context of the recent results from Sudbury Neutrino Observatory (SNO). We present the results of global χ2-analysis for both two and three generation cases with one of the mass states being allowed to decay and include the effect of both decay and mixing. We find that the Large Mixing Angle (LMA) regio...
متن کاملCan the Zee Model Explain the Observed Neutrino Data?
The eigenvalues and mixing angles in the Zee model are investigated parameterindependently. When we require |∆m12/∆m23| 1 in order to understand the solar and atmospheric data simultaneously, the only solution is one which gives bi-maximal mixing. It is pointed out that the present best-fit value of sin 2θsolar in the MSW LMA solution cannot be explained within the framework of the Zee model, b...
متن کاملCharge breaking bounds in the Zee model
We study the possibility that charge breaking minima occur in the Zee model. We reach very different conclusions from those attained in simpler, two Higgs doublet models, and the reason for this is traced back to the existence of cubic terms in the potential. A scan of the Zee model’s parameter space shows that CB is restricted to a narrow region of values of the parameters.
متن کاملEmbed Zee Neutrino Mass Model into Susy
We have seen substantial amount of experimental evidences from solar and atmospheric neutrino experiments that neutrinos in fact have masses. Among the experiments, SuperKamiokande 2 provided the strongest evidence for the atmospheric neutrino deficit, especially the impressive zenith angle distribution. The neutrino oscillation of νμ → ντ provides the best explanation for the atmospheric neutr...
متن کاملNew Trends in the Zee Model
Recent trends in the Zee model are reviewed. Especially, the importance of a serious constraint in the Zee model, sin 2θsolar = 1.0, is pointed out.
