Measurement of atmospheric neutrino oscillation parameters by Super-Kamiokande I
Abstract
We present a combined analysis of fully-contained, partially-contained and upward-going muon atmospheric neutrino data from a 1489 d exposure of the Super-Kamiokande detector. The data samples span roughly five decades in neutrino energy, from 100 MeV to 10 TeV. A detailed Monte Carlo comparison is described and presented. The data is fit to the Monte Carlo expectation, and is found to be consistent with neutrino oscillations of νμ↔ντ with sin(22θ>0.92 and 1.5×10-3<Δm2<3.4×10-3 eV2 at 90% confidence level.
