Description
Determination of the neutrino mass ordering is a central goal of the field of neutrino oscillations. Super-Kamiokande is sensitive to the mass ordering primarily through the resonant oscillations of upward going atmospheric electron neutrinos and antineutrinos. Tau neutrinos are an inherently challenging component appearing in this important region. By using a machine learning multivariate method to constrain the number of tau neutrino events in the electron neutrino samples, we see a substantial improvement in our sensitivity to the mass ordering. We present an updated analysis of atmospheric neutrino oscillations with the inclusion of this tau neutrino constraint.
