Description
The discovery of non-zero neutrino masses guarantees the existence of particles and interactions beyond the Standard Model of particle physics. Possible observational signatures of new neutrino physics include deviations in oscillation probabilities predicted by the PMNS framework; neutrino interactions with undiscovered heavy gauge bosons—Non-Standard Interactions (NSI)—coupling to lepton numbers could modify these probabilities. IceCube DeepCore's sensitivity to atmospheric neutrinos, with oscillation baselines spanning the Earth's diameter, makes it an ideal detector to search for NSI effects in the Earth. We adopt a model-independent parameterization that allows for multiple NSI modes simultaneously and present DeepCore's sensitivity to NSI using 9.28 years of data.
