Description
The energy density of ultra-high-energy cosmic rays is at the same level as that of high-energy neutrinos measured at IceCube, suggesting a plausible common origin scenario. Here, we report a combined fit utilizing data from the Pierre Auger and the IceCube Neutrino Observatories to test this hypothesis. We incorporate flux and mass composition, including 𝑋max distributions, for energy bins ranging from 10^17.8 to 10^20 eV for cosmic rays, as well as neutrino data at the highest energies, including starting events, partially-contained cascades, and through-going tracks.
