Claims

C1strongest claim

conservative energy-conservation arguments allow to severely constrain neutrino loss in most scenarios beyond the strongest existing bounds. By performing a fit to the High-Energy Starting Events from IceCube, we quantify the bounds and study their variation with the energy dependence of the attenuation, the assumed redshift distribution of the neutrino sources, and whether the attenuation affects neutrinos exclusively or not.

C2weakest assumption

The assumption that conservative energy-conservation arguments can be applied to severely constrain neutrino loss despite completely unknown sources and production redshifts, combined with the choice of exponential attenuation form and specific redshift distributions in the fit.

C3one line summary

IceCube diffuse neutrino data constrains neutrino loss from new physics via energy conservation, yielding bounds that vary with attenuation energy dependence and source redshift assumptions while potentially affecting spectral index fits.
