Abstract：
In the context of topcolor assisted technicolor(TC2) models,we calculate the contributions of the top Higgs h0t to e ⁺e ^－→c eν e and compare the results with that of h0t to the processes e ⁺e ^－→ Zh0t→Zc and e ⁺e ^－→γh0t→γc. We further discuss the signals of these process at high energy e ⁺e ^－collider (LC) experiments. We find that e ⁺e ^－→c eν e is very sensitive to h0t,which can be easily detected via this process in the future LC experiments with s=500—1500GeV,as long as its mass below the t threshold. The processes e ⁺e ^－→Zc and e ⁺e ^－→γc can also be used to detect h0t in the future LC experiments with s=500GeV.
