Abstract
We consider the contributions of new gauge bosons to W(t) over barb$ c oupling in the top-color-assisted multiscale technicolor model. We fin d that the exchange of the diagonal extended technicolor (ETC) gauge b oson has no contribution to W(t) over barb$ coupling. Using the CERN L EP value of Rb, We calculate the corrections to the CKM matrix element V-tb which arise from the sideways ETC gauge boson and coloron exchan ge. We find that the delta V-tb is significantly large for a certain r ange of the parameters which might be detected in the Fermilab Tevatro n collider's run 3.
