Ultrahigh-energy cosmic rays particle spectra from crypton decays
We calculate the spectra of ultra-high-energy cosmic rays (UHECRs) in an explicit top-down model based on the decays of metastable neutral "crypton" states in a flipped SU(5) string model. For each of the eight specific 10th-order superpotential operators that might dominate crypton decays...
