Abstract

We determine the neutrino mixing and mass parameters that are allowed by the Super-Kamiokande atmospheric neutrino data in a three-neutrino model with one mass-squared difference contributing to the oscillations. We find that although ν_μ→ν_τ oscillations are favored, ν_μ→ ν_e oscillations with amplitude as large as 0.18 are allowed even after accounting for the limit from the CHOOZ reactor experiment. The range of allowed parameters permit observable ν_μ↔ν_e and ν_e→ν_τ oscillations in future long-baseline experiments.
