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...
متن کاملKamLAND potentiality on the determination of Neutrino mixing parameters in the post SNO-NC era
We study in detail the power of the reactor experiment kamLAND for discriminating existing solutions to the SNP and giving accurate information on neutrino masses and mixing angles. Assuming the expected signal corresponding to various “benchmark” points in the 2 dimensional (∆m2, tan2 θ) mixing plane, we develop a full-fledged χ2 analysis which include KamLAND spectrum and all the existing sol...
متن کاملConstraints 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...
متن کاملMeasurement of day and night neutrino energy spectra at SNO and constraints on neutrino mixing parameters.
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%)....
متن کاملSolar Neutrino oscillation parameters after KamLAND
We explore the impact of the data from the KamLAND experiment in constraining neutrino mass and mixing angles involved in solar neutrino oscillations. In particular we discuss the precision with which we can determine the the mass squared difference ∆m2⊙ and the mixing angle θ⊙ from combined solar and KamLAND data. We show that the precision with which ∆m2⊙ can be determined improves drasticall...
