摘要：

The supersymmetric generalization of the limiting and Gaussian QCD spectra is obtained. These spectra are valid for x much less than 1, when the main contribution to the parton cascade is given by gluons and gluinos. The derived spectra are applied to decaying superheavy particles with masses up to the GUT scale, These particles can be relies from the Big Bang or produced by topological defects and could give rise to the observed ultrahigh energy cosmic rays. General formulae for the fluxes of protons, photons and neutrinos due to decays of superheavy particles are obtained. (C) 1998 Elsevier Science B.V. All rights reserved.
