Some comments on Super-Kamiokande's multi-ring analysis

Abstract

The super-Kamiokande collaboration have used multi-ring events to discriminate between the ${\nu }_{\mu }-->{\nu }_{\tau }$ and ${\nu }_{\mu }-->{\nu }_s$ solutions to the atmospheric neutrino anomaly. We show that the effect of systematic uncertainties in cross sections are so significant that the usefulness of multi-ring data to distinguish between these two solutions is doubtful.
