| Abstract |
| Extensive searches for evidence of compositeness of quarks and leptons have been made using the full set of ALEPH data from LEP running at the Z peak. They include searches for radiative and weak decays of excited leptons, and radiative and gluonic decays of excited quarks, produced either singly or in pairs. Searches have also been made for a scalar partner of the Z boson in all decay modes. No evidence for such states has been found and coupling and branching ratio limits are presented. |
