CORRECTIONS TO THE ZB(B)OVER-BAR AND Z-TAU(TAU)OVER-BAR VERTICES IN A REALISTIC ONE-FAMILY TECHNICOLOR MODEL

By means of the effective Lagrangian approach we calculate the vertex corrections to the Zb ($) over bar b and Z tau tau vertices from sideways extended technicolor (ETC) boson exchange and diagonal ETC boson exchange in a realistic one-family technicolor (TC) model without exact custodial symmetry. We find that the Z partial width Gamma(b) = Gamma(Z --> b ($) over bar b), branching ratio R(b), and tau asymmetry parameter A(tau) increase, all in agreement with present experimental data.
