摘要：

We study the effects of residual non-universal interactions of the top quark with the Z-omicron, which typically occur in dynamical symmetry breaking scenarios. Using recent experimental data from LEP and deep inelastic scattering experiments, we place bounds on these extra interactions under the assumption that the top mass and the Fermi scale have a common dynamical origin. Rather significant non-universal interactions are still allowed. We speculate on the possible theoretical and experimental implications of this result.
