Abstract

In this paper we calculate the effects on the $Zb \bar{b}$ vertex from the virtual charged pseudo Goldstone bosons $P^{\pm}$ and $P_{8}^{\pm}$ in the one-generation technicolor model at the one-loop level. In the parameter space the largest reduction to the partial width $Γ (Z \to b \bar{b})$ is 46 MeV and the maximum correction to the ratio $R_{b}^{MSM} is - 9.6 %$ .
