Can we observe weak anomalous couplings of heavy quarks through three-jet events?

The rates and corresponding jet distributions for the decay {ital Z}{r_arrow}{ital b{bar b}g} and the process {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{ital t{bar t}g} may be sensitive to anomalous dipolelike couplings of heavy quarks to the photon and {ital Z}. In the {ital b}-quark case, after updating our previous analysis on the constraints imposed by current experiments on {ital Zb{bar b}} anomalous couplings, we show that the variation of these couplings within their presently allowed ranges leads to rather minor modifications to the standard model expectations for {ital Z}{r_arrow}{ital b{bar b}g} observables. In the {ital t}-quark case, significant deviations from the standard model predictions for {ital t{bar t}g} production at the Next Linear Collider are possible. {copyright} {ital 1996 The American Physical Society.}
