Contribution

It provides the most complete analysis of Super-Kamiokande-I solar neutrino data, refining measurements and implications for neutrino oscillation parameters.

Findings

Measured interaction rate at 47% of standard solar model

No evidence for spectral distortion or flux variation

Results support active neutrino oscillations within LMA parameters

Abstract

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 charged-current 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 imply active solar neutrino oscillations and restrict neutrino mixing and mass square difference to lie within the LMA solution area.
