| Abstract: | Composite models predict the existence of excited quarks and leptons. We find bounds for the masses of possible excited leptons and for the substructure scale by using radiative corrections at theZ scale. A non-decoupling scenario arises naturally which induces upper bounds on these masses as a function of the substructure scale. |
