Are ultrahigh energy cosmic rays a signal for supersymmetry?

    Research output: Contribution to journalArticlepeer-review


    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 (Formula presented), a (Formula presented)-gluino bound state. The range of the (Formula presented) through the cosmic background radiation is significantly longer than the range of nucleons, and therefore (Formula presented)’s can originate from sources at cosmological distances.
