Generalized Statistics and the Rishon Hypothesis
PD Jarvis, H. S. Green · Australian Journal of Physics · 1983
It is pointed out that the proposal of Harari and others, that leptons and quarks should be regarded as composites, consisting of rishons or quips, can be formulated as a field theory in terms of two fundamental spinor fields which satisfy a new generalization of quantum statistics. The requirement of macroscopic causality determines which of the many combinations of rishons may be observed as isolated particles.
