Has the GZK cutoff been discovered?
The energy spectra of ultra high energy cosmic rays reported by the AGASA, Fly’s Eye, Haverah Park, HiRes, and Yakutsk experiments are all shown to be in agreement with each other for energies below 10 20 eV(after small adjustments, within the known uncertainties, of the absolute energy scales). The...
