Solar Neutrino Precision Measurements using all 1496 Days of Super-Kamiokande-I Data
The results of the entire Super-Kamiokande-I solar neutrino data are presented. The measured interaction rate is 47±2% of the rate expected by the standard solar model and 133±5% of the rate implied by the SNO chargedcurrent interaction rate. There is no evidence for spectral distortion or a time dependent neutrino flux. Together with the rates of other experiments, the Super-Kamiokande results...
متن کاملAstroparticle physics with solar neutrinos
Solar neutrino experiments observed fluxes smaller than the expectations from the standard solar model. This discrepancy is known as the "solar neutrino problem". Flux measurements by Super-Kamiokande and SNO have demonstrated that the solar neutrino problem is due to neutrino oscillations. Combining the results of all solar neutrino experiments, parameters for solar neutrino oscillations are o...
متن کاملThe Solar Neutrino Day/Night Effect in Super-Kamiokande
The time variation of the elastic scattering rate of solar neutrinos with electrons in Super-Kamiokande-I was fit to the day/night variations expected from active two-neutrino oscillations in the Large Mixing Angle region. Combining Super-Kamiokande measurements with other solar and reactor neutrino data, the mixing angle is determined as sin θ = 0.276 −0.026 and the mass squared difference bet...
متن کاملSuper Kamiokande results: atmospheric and solar neutrinos
Atmospheric neutrino and solar neutrino data from the first phase of Super-Kamiokande (SKI) are presented. The observed data are used to study atmospheric and solar neutrino oscillations. Zenith angle distributions from various atmospheric neutrino data samples are used to estimate the neutrino oscillation parameter region. In addition, a new result of the L/E measurement is presented. A dip in...
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 کاملDetermination of Solar Neutrino Oscillation Parameters using 1496 Days of Super-Kamiokande-I Data
A number of different fits to solar neutrino mixing and mass square difference were performed using 1496 days of Super-Kamiokande-I’s solar neutrino data. These data select two allowed areas at large neutrino mixing when combined with either the solar B flux prediction of the standard solar model or the SNO interaction rate measurements. A global fit combining SK data with the solar neutrino in...
