TC2 dynamics and single top quark production at high-energy e+ e- colliders

We give the anomalous $Z\bar tc$ couplings, which come from the top-color gauge bosons, and estimate their contributions to the process $e^+e^-\to\bar tc$ in top-color-assisted technicolor (TC2) theory. Our results show that the production cross-section is of the order of 100–10-1 fb for reasonable ranges of the parameters.
