Extended technicolor theories generate potentially large corrections to the {ital Zb{bar b}} vertex which can be observed in current experiments at the CERN {ital e}{sup +}{ital e{minus}} collider LEP.

Virtual corrections on the Zbb vertex from charged PGBs and the new electroweak data

In the one-generation technicolour model, the one-loop virtual corrections on the Zbb vertex from the P+or- and P8+or- can be rather large; the shift delta Rb=(Rb-RbSM)/RbSM in the range of 0-9.6% in

Possible explanation of the Zbb vertex anomaly in one-family technicolor models.

It is shown that in the one-family technicolor model recently proposed by the authors all the {ital S, {ital T}, and {ital U} parameters can be consistent with the experimental bounds while the observed anomaly of {ital R}{sub {ital b}} is naturally explained.
