Multi-Flavor 10PeV+ neutrino search with IceCube

IceCube, a cubic kilometer neutrino detector located at the South Pole, reported detection of a shower that was indicative of a Glashow resonance initiated by a neutrino with an energy of 6.3 PeV. Observing highly energetic events like this one are critical as they contain crucial information on its originating source. Current literature suggests that a neutrino flux at ~10PeV is key to test a possible common origin of high-energy neutrinos with ultra-high-energy cosmic rays. We present a novel method to efficiently reject cosmic-ray muon background by detecting hit patterns inconsistent with the neutrino hypothesis.  A dedicated high-energy partially-contained cascade selection aiming at detection of neutrinos of 10PeV and beyond will be reported.
