Neutrino mass and mixing measurements at super-kamiokande

The latest atmospheric and solar neutrino measurements from over 1200 live days of the Super-Kamiokande detector are presented. Atmospheric results continue to strongly support the hypothesis of vi, oscillations via the measured deficit of mu - like interactions and the strong dependence of the deficit on neutrino flight distance. Analysis of the data gives best fit 2-component oscillation, parameters (sin(2) 2theta, deltam(2)) = (1.00,2.5 x 10(-3)ev(2)) with X-2/DOF = 142.1/152. In contrast, the no-oscillation hypothesis gives X-2/DOF = 344.1/154. No evidence is seen for a sterile neutrino, and the case where oscillation is 100% into a sterile neutrino is ruled out. 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) all owed regions are excluded at the 95% c.l.
