Solar neutrinos: global analysis and implications for SNO
We present a global analysis of all the available solar neutrino data treating consistently the B and hep neutrino fluxes as free parameters. The analysis reveals at 99.7% C.L. eight currently-allowed discrete regions in two-neutrino oscillation space, five regions corresponding to active neutrinos and three corresponding to sterile neutrinos. Most of the allowed oscillation solutions are robus...
متن کاملSolar Neutrinos: Global Analysis with Day and Night Spectra from SNO
We perform global analysis of the solar neutrino data including the day and night spectra of events at SNO. In the context of two active neutrino mixing, the best fit of the data is provided by the LMA MSW solution with ∆m2 = 6.15 ·10−5 eV2, tan2 θ = 0.41, fB = 1.05, where fB is the boron neutrino flux in units of the corresponding flux in the Standard Solar Model (SSM). At 3σ level we find the...
متن کاملGlobal analysis of Solar neutrino oscillation evidence including SNO and implications for Borexino
An updated analysis of all available neutrino oscillation evidence in Solar experiments including the latest SNO data is presented. Predictions for total rates and day-night asymmetry in Borexino are calculated. Our analysis features the use of exhaustive computation of the neutrino oscillation probabilities and of an improved statistical χ treatment. In the framework of two neutrino oscillatio...
متن کاملGlobal Analysis of Solar Neutrino Oscillations Including SNO CC Measurement
For active and sterile neutrinos, we present the globally allowed solutions for two neutrino oscillations. We include the SNO CC measurement and all other relevant solar neutrino and reactor data. Five active neutrino oscillation solutions (LMA, LOW, SMA, VAC, and Just So) are currently allowed at 3σ; three sterile neutrino solutions (Just So, SMA, and VAC) are allowed at 3σ. The goodness of fi...
متن کاملImplications of Solar and Atmospheric Neutrinos
The importance of non-zero neutrino mass as a probe of particle physics, astrophysics, and cosmology is emphasized. The present status and future prospects for the solar and atmospheric neutrinos are reviewed, and the implications for neutrino mass and mixing in 2, 3, and 4-neutrino schemes are discussed. The possibilities for significant mixing between ordinary and light sterile neutrinos are ...
