Abstract
In this paper we calculate the effects on the ZbbBAR vertex from the v irtual charged pseudo Goldstone bosons P+/- and P8+/- in the one-gener ation technicolor model at the one-loop level. In the parameter space the largest reduction to the partial width GAMMA(Z --> bbBAR) is 46 Me V and the maximum correction to the ratio R(b)MSM is -9.6%.
