Description
The latest atmospheric and solar neutrino measurements from over 1100 live days of the Super-Kamiokande detector are presented. Atmospheric results continue to strongly support the hypothesis of νμ oscillations via the measured deficit of μ - like interactions and the strong dependence of the deficit on neutrino flight distance. Analysis of the data gives best fit 2-component oscillation parameters (sin2 2θ, δm2) = (1.00, 3.2 x 10-3ev2) with χ2/DOF = 124.7/135. In contrast, the no-oscillation hypothesis gives χ2/DOF = 296.5/139. For solar neutrinos, no evidence of neutrino oscillations is seen in the spectral shape or expected day/night enhancement effect. The Small Mixing Angle (SMA) and Vacuum Oscillation (VO) allowed regions from flux deficit alone are excluded at the 95% c.l
