Description

The IceCube Neutrino Observatory has provided world-leading limits on sterile neutrino parameters by looking for a sterile signal caused by matter enhanced resonance in the Earth. IceCube can search for a matter-enhanced sterile neutrino signal using its large and high purity sample of upgoing muon neutrino tracks, with modern reconstruction techniques and a sophisticated systematics treatment. In this contribution, ongoing work to improve the IceCube sterile neutrino search over the 2023 results will be described. New ML reconstructions and classifiers will enable a redesigned event selection with better statistics and more event topologies, and a wide variety of systematics have been updated. These changes, as well as the range of sterile analyses they will enable, will be discussed.
