Very-high-energy astrophysical neutrinos were first observed by IceCube in 2012. Since then, these neutrinos attract many interests by both astrophysicists and particle physicists. These neutrinos are the highest energy particles observed on the Earth, and they travel the longest distance in the universe. This makes astrophysical neutrinos to be very sensitive to any tiny properties otherwise invisible. This includes Lorentz violation, neutrino-dark energy coupling, quantum foam, long-range force, etc.
If such an effect does exist in the vacuum, one would expect additional terms in the neutrino vacuum Hamiltonian, and that modifies the mixing of neutrinos. Thus, astrophysical neutrino flavour may be one of the strongest tools to look for new physics. Queen Mary group is working in IceCube beyond the Standard Model (BSM) to develop better flavour measurement and the framework to look for new physics from astrophysical neutrino flavour.
