The top mass and pseudo-Goldstone bosons at LHC/SSC

Abstract

We consider models where the top mass is built up both from a top condensate and radiative contributions and mass generation in the weak boson sector is dynamical. As a consequence charged and neutral pseudo-Goldstone bosons appear. Their masses are estimated and found to be in a range accessible at LHC/SSC. Also they fall naturally in the region where the standard model requires new physics to appear. A brief qualitative discussion concerning their observability is added. Basically the search can be performed together with the search for charged and neutral Higgses. Particular important would be to discriminate them from SUSY charged Higgses. It is noted that the predicted scalar spectrum cannot be imitated by an extended Higgs sector of the standard model. Extension of the radiative mass generation to the τ-sector calls for the introduction of a new heavy lepton doublet with mass in the region 1–2 TeV.
