Exploring \nu_\tau - \nu_s mixing with cascade events in DeepCore

Understand

The atmospheric neutrino data collected by the IceCube experiment and its low-energy extension DeepCore provide a unique opportunity to probe the neutrino sector of the Standard Model.

• In the low energy range the experiment have observed neutrino oscillations, and the high energy data are especially sensitive to signatures of new physics in the neutrino sector.
• In this context, we previously demonstrated the unmatched potential of the experiment to reveal the existence of light sterile neutrinos.
• The studies are routinely performed in the simplest 3+1 model concentrating on disappearance of muon neutrinos of TeV energy as a result of their mixing with a sterile neutrino.
