Extensive searches for evidence of compositeness of quarks and leptons have been made in the complete set of ALEPH data from LEP running at the Z peak. These include searches for radiative and weak decays of excited fermions, produced either in pairs or singly, and a scaler partner of the Z. Coupling and branching ratio limits deduced from these searches are presented.

Abstract
Extensive searches for evidence of compositeness of quarks and leptons have been made in the complete set of ALEPH data from LEP running at the Z peak. These include searches for radiative and weak decays of excited fermions, produced either in pairs or singly, and a scaler partner of the Z. Coupling and branching ratio limits deduced from these searches are presented.File in questo prodotto:
