    Abstract

    We investigate the possibility that cosmic rays of energy larger than the Greisen-Zatsepin-Kuzmin cutoff are not nucleons, but a new stable, massive, hadron that appears in many extensions of the standard model. We focus primarily on the S0, a uds-gluino bound state. The range of the S0 through the cosmic background radiation is significantly longer than the range of nucleons, and therefore S0's can originate from sources at cosmological distances.
