Abstract

A search for the appearance of tau neutrinos from νμ↔ντ oscillations in the atmospheric neutrinos has been performed using 1489.2 days of atmospheric neutrino data from the Super-Kamiokande-I experiment. A best fit tau neutrino appearance signal of 138±48(stat)-32+15(syst) events is obtained with an expectation of 78±26(syst). The hypothesis of no tau neutrino appearance is disfavored by 2.4 sigma.
