New atmospheric and solar results from Super-Kamiokande

The Super-Kamiokande (SK) experiment has accumulated data on atmospheric neutrino and solar neutrino events and has made improvements in their measurements over the last 20 years. A three-flavor oscillation analysis was conducted with the atmospheric neutrino data in order to study the mass hierarchy, the leptonic CP violation term, and other oscillation parameters. A stronger preference for the normal mass hierarchy was obtained with SK + T2K external data: Delta chi(2) = chi(2)(NH) - chi(2)(IH) = -5.2 (-3.1 was expected when assuming the best fit parameters of the SK + T2K). The analysis of the appearance of tau neutrinos has been updated and a significance of 4.6 sigma was observed. The observation of similar to 84,000 solar neutrinos give precise measurements of the energy spectrum and time variation testing terrestrial and solar matter effects. This data favor a lower Delta m(21)(2) value than that measured with reactor anti-neutrinos by KamLAND by more than 2 sigma, and they determine this parameter in the solar neutrino oscillation fit.
