Is there evidence for sterile neutrinos in IceCube data?

Understand

Data from the LSND and MiniBooNE experiments, and revised expectations of the antineutrino flux from nuclear reactors suggest the existence of eV-mass sterile neutrinos.

• 3+2 and 1+3+1 scenarios accommodate all relevant short-baseline neutrino data except for the low-energy MiniBooNE anomaly.
• We analyze the angular distribution of upward going atmospheric neutrino events in the IceCube-40 dataset for evidence of sterile neutrinos within these scenarios.
• Depending on how systematic uncertainties are handled, we find strong evidence for, or weak evidence against sterile neutrinos.
