Author(s): R. Abbasi et al. (IceCube Collaboration) The flavor composition of cosmic neutrinos probes both the physical properties of their sources and oscillations over energies and distances unreachable by terrestrial experiments. Using 11.4 yr of IceCube data, we analyze the flavor composition of the all-sky neutrino flux from 5 TeV–10 PeV, signif… [Phys. Rev. Lett. 137, 081002] Published Tue Aug 18, 2026
