چکیده

The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates. For charged current events, assuming an undistorted 8B spectrum, the night minus day rate is 14.0%+/-6.3%(+1.5%)(-1.4%) of the average rate. If the total flux of active neutrinos is additionally constrained to have no asymmetry, the nu(e) asymmetry is found to be 7.0%+/-4.9%(+1.3%)(-1.2%). A global solar neutrino analysis in terms of matter-enhanced oscillations of two active flavors strongly favors the large mixing angle solution.

Results from the Salt Phase of Sno

The Sudbury Neutrino Observatory (SNO) has recently completed an analysis of data from the salt phase of the experiment, in which NaCl was added to the heavy-water neutrino target to enhance sensitivity to solar neutrinos. Results from the 391-day salt data set are summarized, including the measured solar neutrino fluxes, the electron energy spectrum from charged current interactions, and the d...

Determination of Neutrino mixing parameters after SNO oscillation evidence

An updated analysis of all available neutrino oscillation evidence in Solar experiments (SK day and night spectra, global rates from Homestake, SAGE and GALLEX) including the latest SNOCC and NC data is presented. Assuming that the shape of the SNO CC energy spectrum is undistorted and using the information provided by SNO we obtain, for the fraction of electron neutrinos remaining in the solar...

Constraints on neutrino oscillation parameters from the SNO salt phase data

The physics implications of the just published salt phase data from the SNO experiment are examined. The effect of these data on the allowed ranges of the solar neutrino oscillation parameters, ∆m21 and sin 2 θ12, are studied in the cases of twoand threeneutrino mixing. In the latter case we derive an upper limit on the angle θ13. Constraints on the solar νe transitions into a mixture of active...

Global 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...

Constraints on Neutrino Mixing Parameters with the SNO data

This paper reviews the constraints imposed on the solar neutrino mixing parameters by data collected by the Sudbury Neutrino Observatory (SNO). The SNO multivariate analysis is reviewed. The global solar neutrino analysis is emphasized in terms of matter-enhanced oscillation of two active flavors. An outline of how SNO uses the data to produce oscillation contour plots and how to include the re...

On the Status of Three-neutrino Mixing

All existing solar and atmospheric neutrino oscillation data are described by the standard two-neutrino formulas with neutrino mass squared differences that satisfy the hierarchy relation ∆m2sol ≪ ∆m 2 atm. We discuss this phenomenon from the point of view of three-neutrino mixing. Possibilities to see effects of three-neutrino mixing and, in particular, effects of CP-violation in the lepton se...
