摘要：

We describe the results of a hybrid matrix-Monte Carlo calculation of cascading of UHE cosmic rays and gamma-rays through the cosmic background radiation fields over cosmological distances. We calculate the gamma-ray and neutrino emission that results from the cascade, as well as the effect of cascading on the primary spectrum. We discuss the results for various cosmic ray injection spectra and primary species. Certain models for the production of the highest energy cosmic rays are ruled out.
