Abstract

We report on the results of a three-flavor oscillation analysis using Super-Kamiokande I atmospheric neutrino data, with the assumption of one mass scale dominance (Δm122=0). No significant flux change due to matter effect, which occurs when neutrinos propagate inside the Earth for θ13≠0, has been seen either in a multi-GeV νe-rich sample or in a νμ-rich sample. Both normal and inverted mass hierarchy hypotheses are tested and both are consistent with observation. Using Super-Kamiokande data only, 2-dimensional 90% confidence allowed regions are obtained: mixing angles are constrained to sin 2θ13<0.14 and 0.37<sin 2θ23<0.65 for the normal mass hierarchy. Weaker constraints, sin 2θ13<0.27 and 0.37<sin 2θ23<0.69, are obtained for the inverted mass hierarchy case.
