Atmospheric neutrino results from Super-Kamiokande and Kamiokande — Evidence for ν oscillations

Abstract

New atmospheric neutrino results from Super-Kamiokande are presented. Results from Kamiokande on upward going muons are also presented. All these data, together with the Kamiokande atmospheric neutrino data give evidence for neutrino oscillations. Two avor $ oscillations, with large sin 2 2 and m 2 in the region of 10,3 to 10,2 eV 2, explain all these data. 1.
