Abstract
We calculate the correction of the TC2 dynamics to the production cross section of the process $e^+e^- \rightarrow t\overline{t}$in the top color-assisted multiscale technicolor model. Our results show that the corrections mainly come from the effects of the top color gauge boson $Z^{\prime}$ in the s-channel. The total corrections to cross sections $\sigma_L$ and $\sigma_R$ are very large; this can be detected at NLC. The total corrections to the polarized parameters PLtand PRt may be observed at NLC in most of the parameter space.
