PROBING THE COUPLINGS OF THE TOP-QUARK TO GAUGE BOSONS

We parameterize the non-universal couplings of t-t-Z and t-b-W in the electroweak chiral lagrangian approach, and examine the constraints on these parameters from the LEP data. We also study how the SLC, Tevatr on, LHC and NLC can improve the measurement of these couplings. Differ ent symmetry breaking scenarios imply different correlations among the se couplings, whose measurement will then provide a means to probe the electroweak symmetry breaking sector.
