Abstract：
In the framework of topcolor-assisted technicolor (TC2) theory, we calculate the contri- butions of TC2 dynamics and the neutral top-pion to top-charm production at the high energy e⁺e^－ linear collider (LC) experiments. Our results show that the contributions mainly come from the neu- tral top-pion π0t. The cross section is of the order of 10^－2 pb in most of the parameter space in the TC2 theory. If we assume that the integrated luminosity of LC experiments is 500fb^－1, it would pro- duce serveal thousand events. So it is possible to detect the signature of TC2 theory at the future LC experiments.
