Abstract: In a realistic effective one-family extended technicolor(ETC)model without exact custodial symmetry, we calculate the one-loop corrections to the Zbb and Zτ+τ- vertices from the sideways and diagonal ETC gauge boson exchange.The results show that both the Z→ bb partial Width Γb and branching ratio Rb and the τ polarization asymmetry parameter Aτ are enhanced by the corrections and are in agreement with the present experimental data.
