Scientific paper

The hypothesis of topological defects (from grand unified and/or Planck scales) as the sources of extremely high-energy (>1018-eV) cosmic rays predicts an unusually high content of γ rays at energies E>~1020 eV (γ/p>=1) and E<~1014 eV (γ/p>~10-3). This can be used as a signature for testing the hypothesis in forthcoming experiments.
