Sensitivity to Non-Standard Neutrino Interactions in IceCube DeepCore

The IceCube Neutrino Observatory is a cubic-kilometer ice Cherenkov detector at the South Pole designed to detect neutrinos in the GeV to PeV energy range. Its in-ice PMT array includes DeepCore, a sub-detector specially instrumented for the detection of GeV-scale neutrinos. DeepCore detects neutrinos that originate in interactions of cosmic rays with the Earth's atmosphere and travel long distances through the planet to interact in the South Pole's glacial ice. These neutrinos forward scatter off charged fermions along their paths, which modifies their effective oscillation parameters. If a portion of these interactions are via particles outside of the Standard Model, the strength of such interactions can be probed by analyzing the impact of the interactions on the measurement of neutrino oscillations with DeepCore. An ongoing IceCube analysis aims to place competitive constraints on the strength of non-Standard neutrino interactions using 9.3 years of DeepCore data.
