Seasonal and energy dependence of solar neutrino vacuum oscillations
نویسندگان
چکیده
We make a global vacuum neutrino oscillation analysis of solar neutrino data, including the seasonal and energy dependence of the recent Super–Kamiokande 708day results. The best fit parameters for νe oscillations to an active neutrino are δm = 4.42 × 10 eV, sin 2θ = 0.93. The allowed mixing angle region is consistent with bi–maximal mixing of three neutrinos. Oscillations to a sterile neutrino are disfavored. Allowing an enhanced hep neutrino flux does not significantly alter the oscillation parameters.

Seasonal Variations of the 7 Be Solar Neutrino Flux ∗
Measuring the 7Be solar neutrino flux is crucial towards solving the solar neutrino puzzle. The Borexino experiment, and possibly the KamLAND experiment, will be capable of studying the 7Be neutrinos in the near future. We discuss (1) how the seasonal variation of the Borexino and KamLAND data can be used to measure the 7Be solar neutrino flux in a background independent way and (2) how anomalo...
متن کاملVacuum Oscillations and Future Solar Neutrino Experiments
Vacuum oscillations are considered for the combined solar neutrino observations, including the Kamiokande II spectrum data and incorporating theoretical uncertainties and their correlations. Despite the conceptual difficulty of the fine tuning between the neutrino parameters and the Sun-Earth distance, 2-flavor vacuum oscillations provide phenomenologically acceptable solutions. There are allow...
متن کاملGlobal Three-neutrino Vacuum Oscillation Fits to the Solar and Atmospheric Anomalies
We determine the three-neutrino mixing and mass parameters that are allowed by the solar and atmospheric neutrino data when vacuum oscillations are responsible for both phenomena. The global fit does not appreciably change the allowed regions for the parameters obtained from effective twoneutrino fits. We discuss how measurements of the solar electron energy spectrum below 6.5 GeV in Super-Kami...
متن کاملVacuum oscillations of solar neutrinos: correlation between spectrum distortion and seasonal variations
Long length vacuum oscillations solution of the solar neutrino problem is discussed. We show that there is a strict correlation between a distortion of the neutrino energy spectrum and an amplitude of seasonal variations of the neutrino flux. The slope parameter which characterizes a distortion of the recoil electron energy spectrum in the Super-Kamiokande experiment and the seasonal asymmetry ...
متن کاملEnhancing the Seasonal Variation Effect in the Case of the Vacuum Oscillation Solution of the Solar Neutrino Problem
We study in detail the threshold energy dependence of the seasonal variation effect in the energy integrated solar neutrino signal of the Super-Kamiokande detector in the case of the νe ↔ νμ,τ vacuum oscillation (VO) solution of the solar neutrino problem. We show, in particular, that for the values of ∆m2 and sin 2θ from the VO solution region, the predicted time and threshold e− energy (Te,Th...
