Abstract：
We calculate the contributions of extended technicolor (ETC) interaction to CP violation asymmetry parameter δ in top quark pair Production, δ = σ[e-e→t(-)-t(-)]-σ[e-e→t(+)-t(+)]/σ(e-e→t-t), in topcolor-assisted multiscale technicolor (TOPCMTC) model. Using the new LEP value of Rb, we give the numerical results. Our results show that ETC interactions can produce significantly effects on CP violation for a certain range of the parameters in TOPCMTC model. For 5 00 GeV<1/2s< 15 00 GeV, the value of parameter δ is in the range of 8. 65×10^－3 ≤δ≤1. 09×10^－2. We expect that this effect may be testable in the future NLC experiments.
