Analysis of upward-going muons and global data
Abstract
In 1998, the Super-Kamiokande announced evidence for the observation of neutrino oscillations based on measurements of the atmospheric neutrino flux. This paper presents the updated results for fully and partially-contained events with 736 days of data, as well as upward-going muon results and a global analysis. Preliminary interpretations of the results in terms of various two-flavor oscillation hypotheses are presented.
