Implications for Solar Neutrino Oscillations from Super-Kamiokande and SNO Data

Abstract

Super-Kamiokande uses neutrino-electron elastic scattering to measure the recoil electron spectrum and zenith-angle dependence of solar 8^8B neutrinos. SNO has measured the 8^8B neutrino--deuteron charged-current reaction rate. The elastic scattering rate, spectrum and zenith-angle dependence in conjunction with the charged-current reaction rate favors active neutrino oscillations at large mixing angles by about 3σ\sigma over the no-oscillation hypothesis and small mixing angles. The analysis is independent of the absolute 8^8B and {\it hep} flux and assumes two-flavor oscillations described by mixing angle and mass2^2 difference. Two allowed regions at large mixing are found.
