Discovery of neutrino oscillations and mass

fig. from www.aip.org/physnews/graphics

With 500 days of data collected in the Super-Kamiokande detector a significant anisotropy was observed in the angular distribution of atmospheric neutrinos. Oscillations of muon neutrinos fit best the observations ( PRL 81, 1562 (1998).

Up-down asymmetry versus lepton momentum (blue lines are expected without oscillations, red with the best fit oscillation parameters). Click here for more plots and figures on atmospheric neutrinos.

  Detector:

  The world largest detector, filled with 50 000 tons of ultra-pure water is located in the tunnel of Kamioka mine in Japan. About 100 physicists from Japan, USA and Poland participate in the experiment.
