SU(4) Preonic Interpretation of the HERA Positron-Jet Events

Abstract

We show that our recent SU(4) generalized ``rishon'' composite model for quarks and leptons, augmented either by the hypothesis of breaking of color SU(3) to ``glow'' SO(3), or by the hypothesis of incomplete color neutralization in very hard processes, leads to an interpretation of the HERA positron-jet events as the production by color gluon exchange, followed by the decay by color gluon emission, of the positron member of a heavy family partner of the positron.
