Solar Neutrino Rates, Spectrum, and Its Moments : an Msw Analysis in the Light of Super-kamiokande Results
نویسندگان
چکیده
We re-examine MSW solutions of the solar neutrino problem taking (a) the results on total rates and the electron energy spectrum from the 825 day SuperKamiokande (SK) data, (b) those on total rates from the Chlorine and Gallium experiments, and (c) moments of the SK electron spectrum. A salient feature of our analysis is the inclusion of the correlations between the theory errors in the global-fit using the data on the total rates and SK electron energy spectrum. Best fit values for the mixing angle and mass splitting are found for oscillations to sequential and sterile neutrinos and the 90% C.L. allowed regions are determined.

Three-flavor MSW solutions of the solar neutrino problem
We perform an updated phenomenological analysis of the Mikheyev-SmirnovWolfenstein (MSW) solutions of the solar neutrino problem, assuming oscillations between two and three neutrino families. The analysis includes the total rates of the Homestake, SAGE, GALLEX, Kamiokande and SuperKamiokande experiments, as well as the day-night asymmetry and the 18-bin energy spectrum of Super-Kamiokande. Sol...
متن کاملDoes the Sun appear brighter at night in neutrinos?
We calculate accurately the number of solar neutrino events expected as a function of solar zenith angle, with and without neutrino oscillations, for detectors at the locations of Super-Kamiokande, SNO, and the Gran Sasso National Laboratory. Using different Earth models to estimate geophysical uncertainties, and different solar models to estimate solar uncertainties, we evaluate distortions pr...

متن کاملSeasonal Dependence in the Solar Neutrino Flux
MSW solutions of the solar neutrino problem predict a seasonal dependence of the zenith angle distribution of the event rates, due to the non-zero latitude at the Super-Kamiokande site. We calculate this seasonal dependence and compare it with the expectations in the no-oscillation case as well as just-so scenario, in the light of the latest Super-Kamiokande 708-day data. The seasonal dependenc...
متن کاملEvidence for Solar Neutrino Flux Variability and its Implications
Although KamLAND apparently rules out Resonant-Spin-Flavor-Precession (RSFP) as an explanation of the solar neutrino deficit, the solar neutrino fluxes in the Cl and Ga experiments appear to vary with solar rotation. Added to this evidence, summarized here, a power spectrum analysis of the Super-Kamiokande data reveals significant variation in the flux matching a dominant rotation rate observed...
