摘要：

As described previously, a new massive gauge boson (X) coupling only to the third family produces a tantalizing pattern of deviations away from the standard model. These include increasing Gamma(b)/Gamma(h) and decreasing the alpha(s)(M(Z)) extracted from Gamma(h)/Gamma(l). We review the status of these X-Z mixing effects. We then calculate X boson induced vertex corrections to Z partial decay widths and to <(tt)over bar> production in p (p) over bar colliders.
