Description
Sterile neutrinos are a popular solution to neutrino anomalies in the short baseline sector. The IceCube Neutrino Observatory is uniquely positioned to search for the sterile neutrino signal separately from the short baseline experiments by looking for the matter-enhanced resonant oscillation of TeV-energy muon neutrinos travelling through the earth into the sterile state. Previous sterile searches in IceCube have yielded world-leading limits in parts of the parameter space, but have also been consistent with the standard model at ~2.2 sigma. This poster will present an overview of the results of the most recent IceCube sterile searches, as well as plans to develop a new, independent sterile search using ν_e CC and ν_μ NC events. This channel will improve the energy resolution compared to the previous ν_μ CC results, providing additional power to the current IceCube results, as well as bring sensitivity to additional sterile parameters for future analyses.
