Nonoblique Corrections in Technicolor Theories Revisited
Abstract
In extended technicolor (ETC) theories, while the sideways ETC boson exchange decreases the width b (Z→ b b), the flavor-diagonal ETC boson exchange tends to increase it, and the ETC-corrected Rb b / had value could agree with recent measurements. The τ asymmetry parameter may also increase in a way consistent with experiment. The weak-interaction parameter receives a correction from diagonal ETC exchange which is just barely acceptable by experiments.
