Add to ORKGWe argue that the present evidence that the spin of the r Is 1/2 is carcumstantial, nd that a spin of 3/2 is not excluded. If the r spin were 3/2, it would have Important maphcatlons for the idea that leptons and quarks were composite states, per-haps allowing an explanation of the existence of three generations Supergravlty ideas could also be affected. Similar Ideas suggest the b-quark could have spm-3/2; we give several ways to test this. Introduction. We have considered in some detail the possibility of constructing and of testing theories in which leptons and quarks are composite states of some other (presumably "more fundamental")objects; such a point of view has increasingly been studied [1-5]
