High-energy Cosmic Neutrino Flavor Composition in the Era of High Statistics - Qinrui Liu (Queen's U., Kingston)

Abstract: Neutrinos of cosmic origin are excellent messengers to investigate the Universe. The IceCube experiment discovered TeV-PeV neutrinos of astrophysical origin which opened a new window to the cosmos. The flavor composition of cosmic neutrinos carries information on the neutrino production mechanisms as well as possible beyond-standard-model effects during neutrino propagation. In the future, with high statistics, features of the flavor composition can be probed with the next-generation neutrino telescopes.  In this talk, I will discuss the prospects of identifying energy-dependent flavor transitions and lifting the degeneracy between neutrinos and antineutrinos with the Glashow Resonance.
