Cosmic‐Ray Showers Provide Strong Evidence of Neutrino Flavor Oscillation
AUG 01, 1998
In the bowels of a zinc mine, 13 thousand phototubes keeping watch over 50 thousand tons of water have provided the strongest evidence yet of neutrino oscillation, and therefore of neutrino mass.

To prolonged ovation at the recent Neutrino ’98 conference in a ski resort west of Tokyo, the Japanese‐American Super Kamiokande collaboration reported by far the most convincing evidence to date of oscillatory metamorphosis between different neutrino flavors. Super Kamiokande is the gargantuan 50‐kiloton water‐Cerenkov neutrino detector buried 1 kilometer under a mountain not far from the conference site. The collaboration is headed by Yoji Totsuka of Tokyo University’s Institute for Cosmic Ray Research.
