We calculate the contributions of the top-Higgs h 0/t predicted by topcolor assisted technicolor (TC2) models to e+e−→tcV-eVe and compare the results with the contributions of h 0/t to the processes e+e−→Zh 0/t−→Z-tc and e+e−→γh 0/t−→γ-tc. We find that e+e−→-tcV-eVe is very sensitive to h 0/t, which can be easy detected via this process at high-energy e+e− collider (LC) experiments with √8≥ 500 GeV, as long as its mass below the tt threshold. The process e+e−→γtc also can be used to detect h 0/t at LC experiments.
