Abstract

Three dependent data samples that discriminate between the oscillations to either tau neutrinos or sterile neutrinos in the region of mixing angle and Δm2 preferred by the majority of the Super-Kamiokande data are presented. Results show that two-flavor oscillation between muon neutrinos and sterile neutrinos fit the low energy charged current data, but do not fit the neutral current or high energy data. More complicated scenarios in which both νμ↔ντ and νμ↔νs oscillations that coexist with small mixing to sterile neutrinos or with much smaller mass differences for sterile neutrinos are considered.
