Implications of ultra-high energy neutrino flux constraints for Lorentz-invariance violating cosmogenic neutrinos
by Peter W. Gorham et al.
[2012/07] "We show that future observations of cosmogenic neutrinos will provide by far the most stringent limit on LIV
(Coleman-Glashow Lorentz-invariance) in the neutrino sector. We derive the implied level of LIV required to suppress
observation of predicted fluxes from several mainstream cosmogenic neutrino models, and specifically those recently
constrained by the ANITA and RICE experiments. We simulate via detailed Monte Carlo code the propagation of cosmogenic
neutrino fluxes in the presence of LIV-induced energy losses."
