LONGEVITY , *COSMIC rays - Abstract
It is proposed that the highest energy ∼ 10[sup 20] eV cosmic ray primaries are protons which are decay products of a superheavy particle, G. The protons may be decay products either directly of a nearby (galactic) G or of a long-lived intermediate particle X which arises from decay of a distant (cosmological) G, then decays in or near our Galaxy. Such scenarios can occur in e.g. SU(15) grand unification and in some preon models. [ABSTRACT FROM AUTHOR]
