Abstract

The previously published atmospheric neutrino data did not distinguish whet her muon neutrinos were oscillating into tau neutrinos or sterile neutrinos , as both hypotheses fit the data. Using data recorded in 1100 live days of the Super-Kamiokande detector, we use three complementary data samples to study the difference in zenith angle distribution due to neutral currents a nd matter effects. We find no evidence favoring sterile neutrinos, and reje ct the hypothesis at the 99% confidence level. On the other hand, we find t hat oscillation between muon and tan neutrinos suffices to explain all the results in hand.
