Pseudo-Dirac neutrinos and relic neutrino matter effect on the high-energy neutrino flavor composition
We show that if neutrinos are pseudo-Dirac, they can potentially affect the flavor ratio predictions for the high-energy astrophysical neutrino flux observed by IceCube. In this context, we point out a novel matter effect induced by the cosmic neutrino background (CνB) on the flavor ratio compositio...
