IceCube MEOWS Working Group Update

This talk presents recent results from the IceCube experiment on new physics searches using a very pure sample of up-going muon tracks produced by TeV-scale atmospheric neutrino interactions beneath the detector. Results on searches for sterile neutrinos in complex models that include a non-zero ??₃₄ mixing angle and decay will be presented along with results on non-standard interactions and on neutrino decoherence. Future upgrades of the analysis will also be discussed.
