SPIN EFFECTS FROM QUARK AND LEPTON SUBSTRUCTURE AT FUTURE MACHINES
R. Rückl · Le Journal de Physique Colloques · 1985
If quarks and leptons are composite on a distance scale Λ-1 the physics at energies larger than Λ will provide plenty of evidence for the new level of substructure. However, already at energies below Λ compositeness should become manifest in deviations from the standard model due to form factors, residual interactions and, possibly, new "light" states. I discuss the virtue of polarized lepton and hadron beams in searching for new interactions and exemplify the production of excited fermions and bosons focussing on spin properties.
