In extended technicolor (ETC) theories, while the sideways ETC boson exchange decreases the width {Gamma}{sub {ital b}}{equivalent_to}{Gamma}({ital Z}{r_arrow}{ital b{bar b}}), the flavor-diagonal ETC boson exchange tends to increase it, and the ETC-corrected {ital R}{sub {ital b}}{equivalent_to}{Gamma}{sub {ital b}}/{Gamma}{sub had} value could agree with recent measurements. The {tau} asymmetry parameter may also increase in a way consistent with experiment. The weak-interaction {rho} parameter receives a correction from diagonal ETC exchange which is just barely acceptable by experiments.
