Description
The IceCube Neutrino Observatory is a neutrino telescope built into the ice at the South Pole. IceCube observes “tracks” produced by charged current (CC) interactions from astrophysical and atmospheric muon neutrinos. Unlike “cascades” from electron neutrino CC, and other neutral current interactions, the energy resolution of tracks is limited by the track length contained within the detector. Due to recent machine-learning-based advances in reconstruction, the precision of the neutrino energy reconstruction for TeV-scale track-like events has improved significantly. This opens up a wide variety of searches for Beyond the Standard Model Physics, including improved searches for a sterile neutrino and studies of the flavor composition of Galactic neutrinos. Current analyses and recent results related to these searches are discussed.
