Radiative Corrections and Composite Weak Vector Bosons at LEP100/SLC Energies

  • Fawzi Boudjema
Part of the NATO ASI Series book series (NSSB, volume 233)


We discuss to which extent the idea that the usual weak vector bosons are composite can survive the stringent tests of precision measurements at LEP100 and SLC. It will be argued that, once the the universality of the weak coupling has been implemented within the composite picture for the observables at the Z peak, one recovers the bulk of the radiative corrections which one usually associates with the the standard model. The discrimination between the SU(2) × U(1) theory and composite W’s can be achieved if one can probe the Higgs sector of the Standard Model or alternatively the additional vector bosons predicted within the composite scheme. This is within the spirit of the B-R-V (Boudjema-Renard-Verzegnassi) strategy that unambiguously identifies models with extra vector bosons once the uncertainties due to the yet unknown parameters of the SU(2) × U(1) theory (heavy top mass, ρ parameter, etc...) have been eliminated.
